When it comes to getting bbs stuck in the spring, my friend had that same issue and i took two tweezers and fiddled with the bb and i managed to pop it out through the bb hole so it is possible but you will have to move the bbs into place with a very small and thin tool. you will definitely need to sandwich the bb in between your two tools or else it will move when you try to pop it out of the bb hole. Now if your bb manages to get to the very bottom of the spring then i don’t believe that you will be able fix it but as long as it doesn’t get stuck at the very bottom of the spring then you can fix it
Yeah I can see how that can work, and hopefully the spring isn't mangled.
This was my issue. Screwed up a spring doing this. So I had to buy another mag after spring was trashed. Still trying to find another spring
@@anthonysanders4326 there should be spring manufacturers out there that can provide quasi similar springs
Duck duck go ‘airsoft’ loading magazines spring mechanism / ex springs.
Was bored and felt lil baby Jesus move me towards gentlemanly deeds…- and to aid a down’d weapon soldier
@Anthony Sanders contact crosman they sent me a spring free of charge
Nice work man! Thanks for the shout out. Subbed
Thanks xD
This is very helpful man thanks for making this type of video
hope to see more of these tip and trick videos
Thanks for the feedback😃 If you ever encounter a problem you can't fix with a Google search lemme know!
If your sitting at the table and jawing with the wife while your loading her mag and you inadvertently shove a BB into the spring, it's not wrecked. Simply take the screw out that holds the spring into place and take the spring out. Once the spring is out you can remove the BB's from it without damage. I've been working on scuba gear for years. Sometimes when you have a pressure leak the o ring needs to be replaced. For a BB gun, take the offending ring to your local hardware store. You can probably find a replacement for less that 25 cents 'Merican .
I agree with you 100% on this my friend xD I was hoping people realize the ez fix once the mag is disassembled and the spring (and bbs) come out.
I myself have worked on stuff as small as a vacuum pump all the way up to 80ft long 8ft diameter autoclaves xD. Not everybody has tinkering experience hehe.
Is 2 magazines since I can just afford that second🫡 a good start for getting out practicing muscle memory with the DPMS full auto; red dots
I just ordered an R1 and was going to order mags. Outstanding video. Thank you so much. I just subscribed.
Nice! xD have fun plinking and the feedback is much appreciated!
I just want to back up the diagnosis and to let everyone know that this is 100% accurate and true. Thanks for sharing what you have learned. We are pretty much on our own when it comes to fixing our airguns so anything we can learn with diagnosing and fixing is very very much appreciated. Thanks again.
Thanks for the great feedback! Always glad to help out xD
Helping people get the most out of their plinking sessions is my goal. Like you said, nothing guarantees perfect plinking right out of the box, but with a little tinkering and TLC you can rest easy you didnt waste a couple 100 bucks hehe.
Great video, I made a special screw driver, tightened up the number two cylinder and no more wasted CO2. Thanks a lot!
Sweet! Keep on plinking! xD
Very helpful, thank you for the insight.
Thanks for the props even though my video is longwinded xD
Hey bro came across your video and it’s cool. I don’t have any issues with the three magazines I have so far but I’ve only shot maybe 10,000 bbs. Which rifle do you have? I was thinking of giving the rifle a good cleaning but can’t settle on which product to use? Everyone says to use silicone spray or something like that but can’t find one that’s just silicone? Do you break it down when you clean yours or how do you exactly do it? Thanks
Aye, a couple drops of silicone oil in the bolt carrier and on the seals should be enough to keep it lubed. I usually will just wipe everything down with a papertowel until it wipes clean then give everything a sheen with silicone oil, then one drop on each seal and one drop on one of the springs in the fcg. Many will say you dont need to clean the barrel on an airgun but I pass a cleaning cloth regularly and you can definitely see a difference when you shine a light before and after. These things seems to run regardless xD I am just missing an R1 right now.
Dont use the spray stuff, those are usually industrial grade with additives, get regular crosman silicone oil or the rws bottle with the extended spout thingy.
Edit : yes i do perform a basic field strip to clean everything
Good work bruh
Thanks for the props, getting ready for part 2, I have a couple mags that keep acting weird.
Co2 tip really helped I wasted 20 of them things just trying my hardest to get them in
Sweet! Glad to help iron out those plinking sessions xD
love this very good info here.
Thanks! much appreciated xD
By the way, I bought the Missus the 300 round mag. It's worth the investment. You just have to mess with it some to figure out how it really works. She can load that one all by herself now, which frees me up to do some shootin'..... At least, when I can get my SBR from my son. Lol
Aye, thats why I didnt delve too much into the QR mag, I am pretty sure the one I have is just acting weird.
Hope your son's B-day is coming up, so you can get him his own and then plink duel xD
I have an an AK1 with a magazine that is stuck in the rifle. Tried pulling hard and wd40. No Luck. It appears to be stuck on the side opposite the catch that holds it in. When I push the release lever it comes out less than 1/8" on the catch side. any ideas?
Are you pulling straight down? Unlike a real one they dont require to clip in at an angle.
Seems like there is a streak of bad mags out there, you are the 3rd in the past couple weeks with a stuck mag. Can you confirm there are no bbs wedged between the mag and the inner barrel?
My mag has a problem in the top of the magazine the thing that does the blowback randomly snapped and theres a gold circle and now the blowback now shooting semi auto or full auto and i have to manually charge the slide what do i do
There should be a black rubber seal between your gold part and the broken part. I would guess the air pressure is escaping in too many directions and doesn't have enough energy to push the BCG all the back forcing you to charge it for every shot.
Idk if it'd be the solution or not but I got the crosman ak1 BB gun and while reloading I accidentally dropped the magazine and it still works but it's just harder to take in and take out and was wondering what the problem could be. It looks perfectly fine except at the top of where the BB fires, there's tiny tiny dents on it and a tiny bit of the rubber where the firing pin of the rifle hits is poking out just a tiny bit and was wondering how I could exactly fix it
I have an ak1 in the mail, ill see what the mag looks like next week. For sure though any deformed part might create additional friction in the magwell. Wish i could see the condition of your rubber piece, if it's not damaged and just sticking out you need find a way to re-seat it.
Excluding the dropped mag part..... lol
From comments from other viewers I can relate that the problem of the ak mag not dropping free stems from a valve problem in the mag that causes the valve to jam in the "chamber". So you need to empty the co2 and relieve the pressure on the mag valve so it can drop free.
Hope this helps, sorry it took so long, you can contact crosman and hope they replace the mag.
Great vid, very helpful, and informative.
Thanks! glad to help a fellow plinker get the most fun out of their purchase xD
So my issue with three different magazines is the hammer splitting the valve cover in two. Forgive my lack of technical knowledge and description here..basically on the top of the magazine facing the firing mechanism, there is a metal plate with one screw holding it to the magazine.. I have broken three of them in half. Once they break, the magazine will not feed bbs and the blowback action fails.
Im old, but new to this hobby, it was to the dpms sbr that I owe the credit to, for piquing my interest. So fun. It took about a week until I was All In, scope, red dot, bipod, quick reload magazine, and an extra standard magazine…not cheap, but it had a lot of great reviews so, lets go.
The first mag failed in a week, the quick reload magazine took
about three weeks, and finally my original magazine failed.all split this plate..no replacement part that I could find anywhere..not a lot of info out there on this type of failure either, so I’m left with no choice but to replace the whole magazine (?) anyway
Anybody else have a similar issue? Are there any diy Fixes or explanations as to why this occurs?
Yeah this does happen to others, although I never heard about each mag breaking one after the other. Have you field stripped the airgun to make sure all the components are properly in place?
This is most definitely an airgun issue and not a mag issue. If possible I would maybe try and get it replaced. If not, a full field strip is in order, you need to make sure everything is clean and in its proper place.
As to why it happens is hard to say, I have 5 of these and multiple mags, and I only have 1 broken bolt catch.
If the buffers in the lower extension (the stock part) are not being stopped by the retaining pin they potentially could be slamming into the firing pin and the BCG assembly too hard, which would maybe crack that part.
If you plink in the sun and let the mags warm up you could be running a supped up rifle but the internals are not built to handle the increased energy and could break.
You can verify the "hammer chip", it is the little black knob thingy on the end of the hammer inside the BCG. that little black chip should only protrude by barely a mm from the end. Any longer than that could be increasing energy dumped onto the mag valve.
Hope this helps, my videos should help you get through the field strip process, I cover everything with no editing so you guys can follow along.
Aye bro what do you call that one peace that pokes the co2 and I think I tightened it up a bit to tight and broke the tip it's broken
Check out my complete assembly video, I have close ups on the piercing needle. It does look to have an angle to it and I show how to tighten it.
Hope it is not damaged.
I took one of these apart. Looked liked a ball check valve on #2 C02 port.
Indeed, i have a full breakdown and an assembly video out since I made this one.
I have an AK 1 bb gun and my magazine is stuck. same problem. I have an an AK1 with a magazine that is stuck in the rifle. Tried pulling hard and wd40. No Luck. It appears to be stuck on the side opposite the catch that holds it in. When I push the release lever it comes out less than 1/8" on the catch side. any ideas? is i fix this at home. sending the gun back is a big problem.
Couple questions.. Does the magazine release button clear the metal catch completely?
If you put fresh co2 in it does the bolt cycle properly? If something is broken or misplaced in the blowback mechanism potentially the firing pin could be protruding into the mag. (i was able to pull my mag out even with the trigger actuating the firing pin)
The only other part in there is a little catch/tab for the magazine follower and lockback on empty function. If this little tab is broken or bent out of place it most definitely could interfere with magazine removal. Just to make sure.. you need to insert and remove the magazine vertically unlike a real AK where you have to "rock/hinge" it in. You can access the bb follower and spring if you gently remove the plastic part that retains the spring in place, the spring and follower should fall out on their own, if the follower wont fall out it is most likely jammed by the little bolt catch tab inside the mag well.
@16:04 the check valve side- green seal on every R1 at my local TSC was faulty. I actually did watch a video of a dude getting into them but it's just a seal and its apparently very difficult to put back in. I gave up on em. I bought the thing for me and my nephew. Actually, I was able to get a few seals and it works with 1 co2 cartridge but we moved on.
Do you get into PCP airguns bro?
Not yet, being from Canada I would have to register any worth having (which means keeping it locked and range only shooting and all) and I'm kinda keen on getting a long range bolt action for 1km shooting as my next big investment. So the quality airgun precision shooting kinda takes a backseat to real firearms. If I ever have a big enough property I would definitely get into it though lol
Hi, hey I was watching your videos and I was going to take my gun apart and noticed the pin is missing. Not sure when I lost it. It's been in storage for 2 years. We moved but I want to replace that pin. I don't know what it's called. I took a picture but I don't see how to upload a picture to you. Do you know where I can get replacement pins? It's one of the black ones that you push it in and then just pull it out to remove the lower from the upper part of my bush master CO2 BB rifle
That would be the front pivot pin or the rear takedown pin. Unfortunately crosman has not opened up many of their parts for sale individually yet. You can try searching online or your local airsoft shops for a replacement part, the fit should be pretty darn close. You could even try a real one depending on prices.
Those 2 pins technically serve no other purpose than to keep the upper and lower receiver together. Temporally you could jerryrig a fix with anything that will keep the two receivers snug and securely together, I would try to avoid anything that could carve grooves in your crosman holes.
Hi my name is Willie I recently purchased the QR magazine which is the 300 capacity which I've had trouble with sometimes it would work it would use both canisters sometimes it wouldn't so the original I had the same trouble so I started using it more often the original works fine now but the QR the I started taking it apart and of course I avoided the warranty but I can't find parts that's what my question is I've contacted crosman directly and they have no idea where to get parts seals is what I need I actually broke one of the retaining rings which are cast they're very cheap and I started to strip it and then bad things happen anyhow I'd like to find parts please let me know how thank you great video by the way
Oof, tough break. Unfortunately crosman has not pumped out many spare parts for these yet. If you have a friend with a 3d printer and decent material you can maybe get one 3d printed, not sure if that is overkill.
Any solution that could keep the co2 centered as you pierce should keep it running. When I tried taking out the green seal by the bottom it was really tight and I gave up, Maybe a properly sized o'ring will do the trick. Just make sure the tip of the canister gets centered when piercing so it ends up flat on the seal.
I have a broken part of my magazine(dpms sbr), it's like a metal gasket that goes around the o ring where the gas exits towards the bb and the recoil system. Where can I find it?
I haven't seen that for sale as an individual part yet. If crosman customer service won't replace the magazine you could probably tinker a fix, it seems like the only purpose of that part is to hold the gasket in place.
I have the same problems
Thank you for the informative video! I have a question. Mine leaks from the second slot and from the valve at the top. whats wrong with it. Also, it rattles from the top when shaking it
The second slot leak should be fixed by tightening (just a little) the ring on the seal.
But that rattle in the top valve is not good, there shouldn't be any. If the assembly isnt incredibly loose I would bet there is something broken inside. You could try tightening the brass plate on the valve side, but if it is already snugg and it still leaks the valve needs to be opened and inspected.
You can follow along with my disassembly and assembly videos.
@@RWMAirgunsmithing thank you very much
My ABR is less than a week old and now it continues to fire CO2 even when the magazine e is completely empty. This wastes CO2. How can I fix this issue?
Does it do it with fresh co2 (always), after 2 mags? or after 5 mags?
and are you full auto mag dumping?
also.. what temp environment (do you leave your mags bake in the sun) are you plinking in?
sorry for stupid questions but some problems are rarely caused by just one specific thing.
Would these mags work in a 1st gen mcx rattler?
Great video…..thanks
Thanks for watching, hope this helps you plink more xD
I got bbs stuck in the spring and managed to completely destroy my spring where can I purchase another spring???
I would recommend trying crosman customer service first. From what I've seen in the comments apparently there is a good chance they send you one or replace your mag.
Do you have a video of you taking it apart? I have a bb stuck in the spring. It came out of the box like that.
Wow that is crazy! I am currently working on a part 2 for the mags. I'll include the full breakdown.
Until then you can checkout the link I put in the description. Its pretty easy to remove the plastic covers and it is only one screw holding the the bb follower spring in place.
Hey btw I pinned a comment for the "bbstuckinthespring" problem. I would venture it is the easiest solution with no disassembly.
Does anybody know where I can get a replacement spring for the bb follower?
Unfortunately crosman does not sell parts (except like 3 or 4 ). You can buy springs online though, anything with the same diameter and quasi similar thickness should work. Maybe airsoft shops would stock springs that might fit.
I think I damaged the piercing needles from over-tightening my co2...the co2 just shoots right out wasting all the gas in seconds. Is there any way to fix or replace the green seals or piercing needles?
Can you visibly see the piercing needle is crooked or flattened? And which port does it empty from? The same as the co2 or the other port?
@@RWMAirgunsmithing It looks as though the needle on the first valve is slightly seared on the edge and that seems to be where the gas is shooting out. If this is due to over-tightening then I'm afraid I voided my warranty for sending it back
@@argyleantiques9943 hmm the green seal should take care of a leak from the needle. If you screw in the first one and it empties out near the piercing needle than most likely the culprit is the tightening ring. You need to seat the seal a little more. Usually piercing needle problems come with a drop in co2 during shooting, not loading.
@@RWMAirgunsmithinghaving this same issue and I see the first valve is flattened
@@jamari777 that sucks, you guys can try customer service but I don't know if they replace piercing needles. Not sure if you "drop" your co2 in but treating mechanical devices properly is a big part of prolonged use. I have over 3 dozen assorted mags and I go through boxes and boxes of co2 and never had any issues.
Is that fixable can I fix the pin that fixes the co2tanks
Think I answered your other comment, please go check out my disassembly and assembly videos, the piercing needle is beveled.
Was the O' ring on the co² plug lubed up?
If not?
I suggest you grease it up.
It will increase the FPS
The green seal around the piercing needle? The only orings that can affect fps would be the ones inside the actual valve, if they for some reason impede the valve cycling. Considering there are no leaks.
I need help because my AK1 is not letting me take out the mag, it only inches out a tiny bit
Unfortunately my 3 mags and ak1 are working flawlessly. I have inspected the mechanism (others have had the same problem) and the only thing I can see that could bind up a mag is the bolt catch mechanism.
I think maybe contacting crosman to see if they will warranty it would be the best bet. I do believe if it is jammed something is crooked or broken inside. (I might be wrong)
@@RWMAirgunsmithing so it turns out that the mag the ak1 came with is broken. I bought an extra mag with the ak1 and it works flawlessly but the mag that's broken will only come out after all the CO2 has been used up. There also seems to be a slight hissing sound when I take the defective mag out. On another note, I'm not in America and I bought the gun not directly from the Crosman website.
@@overlyzealous274 ah thanks for the feedback! Good to know it is the mag and not the airgun. Ill try and find the comments from other plinkers to let them know.
How do you turn the single shot version into full auto?
Not impossible, but not an easy "snap your fingers" fix, you would have to make your own "disconnector" and replace the part in the semiauto FCG that is modded so the "BCG" catches on each shot, I am about to record a full break-down tutorial.. I'll make sure to point it out.
So far I do not think Crosman sells these parts yet and probably never will seeing as it would be too easy to mod and hence eliminate their product from the non full auto markets, but you can see on the parts list there is a semi auto and a full auto part.
Hello. Thanks for the video. My second co2 cartrige isnt charging. I unscrewed little pin and oiled it, but no help. When I put only second co2 nothing happens and it doesnt go anywhere
By little pin you mean the set screw on the side of the magazine or the piercing needle for the co2?
Kinda sounds like one of your retaining screws holding your co2 seal and piercing needle is too tight and jamming the internal check valve. Did you perform Big J's proof video I linked in description?
@@RWMAirgunsmithing yes, set screw on the right side. I see that second needle is little high and may be this is the problem
@@georgesharvashidze7338 lemme know how it goes xD btw I think I said it in the video but make sure you use proper fitting tools, dont go in crooked.
@@RWMAirgunsmithing of course 😂
@@RWMAirgunsmithing I just did what you say and now when i insert first co2 it comes from second needle xdd
My R1 mag spring broke, what should I do cause i dont want to buy another mag (everything else works fine
You can replace it with any spring with similar size/stiffness. You could probably find one with a few google searches, maybe even check out airsoft shops, they usually have plenty of parts for all their models.
@@RWMAirgunsmithing do you know the spring dimensions? I bought the wrong size & couldn’t find the size when looking it up
Love the airgun. Mine shoots low and to the left. Do you know how I can correct the sight for this issue?
Hmm, what sights are you using and how far out are you?
Also, vortex optics has lots of great videos, they have many about how to zero your optics.
Greatly appreciate your response.
@@rogerbarthe3734 lemme know how it goes, i might be able to help zero it in but, tbh, there are plenty of great videos on youtube. The procedure for airgun scopes is the same as for a real firearm.
Ok, this doesn’t pertain to this mag but I have a glock 17 replica and when I install the co2 into the mag all the air comes out, I do put a drop of air gun oil but doesn’t help, any info on this? Picked up another mag works great but at $50 I would like to fix the problem.
🤷🏻♂️🤷🏻♂️🤷🏻♂️
Oh, and it’s not a new mag, it did work great but now not so much.
@@tommanning7337 if it completely discharges out the top of the magazine then you need to tinker with the valve. If you take it out with an "airsoft valve" tool you can clean inside, re-seat the o-ring, put a drop of silicone oil and then snug the valve back in.
If it is just a slow leak , try putting a drop of silicone oil down the top of the mag directly into the valve while the co2 is slow leaking out. Let it sit and see what happens.
@@RWMAirgunsmithing yeah, it comes out instantly
@@tommanning7337 yeah, need to take out the valve, You can "jerryrig" a tool to unscrew it but I would recommend finding an airsoft shop and buying a valve tool.
The oring inside might be mangled, but if not just a good cleaning and lube job should get it back up and running for at least 6 to 8 co2.
edit : in my experience you will need to unscrew the valve and clean it every half dozen or so co2.
@@RWMAirgunsmithing awesome!!! Thanks man, I’ll mess with it and see what happens.
THANKS!!!!!!!
Ok. So thanks. But how u put those 2 pieces on the top back into place?
The bolt catch mechanism? The long bit goes on the left and the smaller piece on the right, with part numbers facing up, they should just fall into place.
Help me mine will push bb a little to far up causing jams it doesn't stop in the right position it is half way as if a half moon right were the bb hole is located
You are the second in a week with this problem! I've noticed the bb is a bit off center but never had issues. I will start prepping a part 2 for these mags.
I have come across this problem, the mag is not seating properly, it clicks in but is 1mm low.
I made a mark on the magazine and compared it to a functioning crosman, the mark disappeared under the magwell. I fixed my problem by simply inserting a mag over and over VERY FIRMLY but not violently. After about a dozen times the mark disappeared under the magwell, now I have zero feeding issues.
I have a QR mag that shoots co2 out of co2 chamber 2 when Im loading chamber 1. Could you make a video on the qr mag problems? I was hoping to fix it, shipping would take forever and be a challenge, Im way out in the pacific. Please help.
Ok so you may have addressed it in this video, apologies. so if Im dumping gas out of 2, then I should try to tighten two oring assembly. cant seem to find a flat head wide enough, but I will give that a shot. thanks for your video.
@@greyone308 Yeah, I think maybe that number 2 is slack. Might not take much tightening to get it working. Hope it works and you dont have a defect mag and watch out for the piercing needle! hehe
@@RWMAirgunsmithing Thanks so much, just found your channel. Will sub since you help personally.
So have you had a chance to do a video on the Hatsan Invader Auto .25? Its a great gun on all levels. I need to know how to disassemble, how to modify, how to remove the front barrel shroud, etc.
ALso the new A400 is coming out, worlds first. Im dying to get one, do a video on it if you havent already, I wanna know everything, any major issues to look out for. at 400$ they arnt that expensive, but money is tight, and so is the wife..... smiley face, its the next one I want, and if it is what they say it is, and works great, who wouldnt want several?
Thanks
@@greyone308 Sorry, I am in Canada, anything over 500fps and 4.2ft/lbs needs to be registered making purchasing for fun a little tedious. Needless to say I prefer to save my registering for when I buy real firearms xD
@@RWMAirgunsmithing well that stops the Invader, but I think youll be able to get a Barra A400. CHeck them out, full auto from a battery. Ive been waiting my whole life.
Hey, i see that u know this stuff i just got dpms and my mag is defected, when i put co2 into first slot it dumps it thru secound, if i want to use mag i have to put emty co2 into secound slot and then put full co2 into first slot, what do you sgest to do in this case
Most likely the check valve mechanism isnt seated properly by the piercing needle retaining ring.
Follow the instructions in the video, and gradually tighten the ring, you might not need much, dont over do it so you dont squeeze it.
So the secound slot has to be tighten more then first, because now they are tightened equally and that secound one leaks
@@pauliusdorosenka7036 I wouldn't worry about making them equally tight, the goal here is to find the sweet spot. You might have to waste a co2 and perform Big J's video to dislodge the check valve.
Ok that valve adjusting actualy helped and i reloaded both co2 😁 now i would see if they both are using, how many mags can u get from 2 co2 cartriges ?
@@pauliusdorosenka7036 nice! If you are leisurely semi auto plinking you can expect a good 4-5 mags with good power then maybe the 5th and 6th you will start noticing. If you full auto dump repeatedly it will be less. You will find out sure enough when you're done plinking unscrew the co2 xD
You really need to show us if both CO2 cartridges actually emptied. I have 3 magazines and none of them actually work correctly. Meaning it only uses the cartridge on the left. And when I go to replace the left cartridge, the one on the right side gasses out. At that point its useless to change the right side one and just replace the left one, and leave an empty one in the right side. I have a solution though. I plan on marketing it to users of the DPMS SBR. It not only corrects for and eliminates the use of C02, But is also upgrades the unit to 1100 psi PCP air(vs 900 psi CO2). Its a great adaptor. Easy to install, and upgrades to 13 cubic inches of air. Now it really cranks.........I plan on launching sales sometime in 2024 or early 2025. I still need to work out a few logistics first, and launch the LLC. I figure there are around 1 - 2 million of these guns out there that need this mod.
If the second slot empties out it's because the ring is too tight most likely. The seal/piercing needle assembly is keeping the check valve (just a small bb) jammed.
You can buy a HPA adapter from pyramydair, just watch out for the power factor as too much psi will break the airgun internals. Hehe
Whenever I load my CO2 (where it's indicated first), it leaks and depletes all my CO2, so I start with the right side instead. In fact I only fire mine with 1 CO2 just the right side only. Some must be stuck.
Ya , for sure something is getting stuck... thankfully these guys run on one co2 only.
I plan on making a sequel to this video in which I get to the bottom of that interior check valve.
Until then, I highly recommend following the procedure on Big J's channel and after that trying to tinker with the co2 piercing needle ring.
What's happening with co2 leaking out the right side is a really small round ball barring that's not seating right! What's supposed to happen when you load the co2 that says first is the pressure builds up within the shared chamber and that pressure is supposed to push that little ball barring against a seal that on the opposite side of the piercing valve. Sometimes a bit of dirt or whatever it may be gets in the way and causes it to leak past.. if you get a blow gun with the curved metal tip and some pel gun oil, put a couple of drops on each peircer valve and then with the blow start with the the first one and gently apply a bit of air to that valve with the blow gun tip covering the peircer valve and sitting tight again the green o ring. Just be careful not to bend or break the peircer valve tip. Then move to the next one and repeat, but adding more air pressure as you go.. the only reason I say start gently with the air is to make sure you get that oil in there and not all over you or wherever else it may blow onto waisting the oil.. . Also one more thing ,I noticed you mentioned you have never took apart the top valve chamber section. Well I have about a hundred different times I also make my own custom valves almost identical to the factory valve, with the exception of my valves will get you running at anywhere from 600fps to upwards of 1200 fps.. I make three different valves witch all range from above said numbers ! Cheers guys and happy air gunning
I would add some picks with numbers but there's nowhere to attach said file here lol
I also forgot to mention that you can tighten the retaining collar ring, but again be very careful with those as well because there very soft metal and will strip out and in some cases break in half !
Thanks for this. Shot mine in the desert once, then it jammed!
Glad to help out! Was it the spring that jammed? or just dusty environment and the airgun didnt like it?
@@RWMAirgunsmithing I believe it’s the spring. I haven’t had a chance to service and clear it since seeing your video. It wasn’t very dusty that night. I’ll be clearing it soon. Thank you for the video and the reply!
@@motosporttouring If you ever figure out what the issue is and got the time to share, feel free to post here!
@@RWMAirgunsmithing I will for sure!
@@RWMAirgunsmithing figured it out, but not in this gun. I also recently got the Crosman fully auto PFAM9B. Same thing happened. I load too many bbs at once causing the spring to not go into the slot so it can push bbs. It jams there, but once I take some bbs out, it’s good.
Any idea what is used to make the gaskets on the CO2 ports?
You mean around the piercing needle?
@@RWMAirgunsmithing yes
@@d0ntReadOnMe108 there are only the green seals visible from the underneath when you look at the piercing needles, one for each co2.
I'm not sure of the exact material, probably some type of silicone, crosman uses these types of seals on multiple different models.
Cabelas has a sale on the DPSM SBR , you think any of these “gun laws” will effect the BB or Pellet community ? ( I ordered one just in case lol )
Canadian speaking !
Hard to say, they might make them semi auto only like the UK and others.. only thing we can do is not add fuel to the fire, respect local regulations and don't bother the neighbors hehe
UPDATE : after a bit more digging there does seem to be a section in the new bill targeting low power airguns/airsoft that look like real firearms. Order now or maybe forever hold your peace lol.
@@RWMAirgunsmithing bro I’m getting mine shipped today I’m so lucky ! Lol good timing eh
@@RWMAirgunsmithing thank you for the info
@18:08 haha. I tried. It would work randomly.
I remember cutting myself a lot though. There's some sharp pieces on the R1.😂
There's just a cone shaped plug between the two cartridge ports. Inserting the First cartridge presses the plug and it shuts the line so the secondary cartridge port does not let gas out. But the plug sometimes jams itself shut - especially if only using one cartridge at a time. Letting gas outta the first cartridge port, after both cartridges are installed, the secondary cartridge's gas presses easier the plug open since reduced counter pressure by the leaking first cartridge.
I had this plug jammed on one of my mags at some point due to often using only one co2 cartridge in the First port. But by installing an empty cartridge in the First slot first - and using a full cartridge in port #2, the plug always gets pressed open in use by only one co2 cartridge.. I often shot my DPMS with only one cartridge - whenever I just wanted to do a quick shooting test or something..
Nice, when I empty mine I always unscrew the "first" one first, so the second co2 pushes the valve as it empties out. These things are good for over 150 rounds when semi -auto plinking, Kind of a shame they are so finicky.
A little "trick" I started adopting when switching around multiple unmarked mags... I load my co2 and give a little burst on full auto, it seems to dislodge and "wake up" that check valve.
You didnt edit,,,,,,interesting though,...i figured out the first day i had mine it performed poorly and lacked power,.. till i backed off the co2 just like you said,..then got several more rounds through it
I know! I'm pretty much as green as it gets uploading and making videos. Working on it xD I practiced a bit, but I think I need to outline my talking points and stick to the script xD
Glad you get max co2 outa your mags hehe, took me a while because of the multiple magazines!
What if mag spews out co2 when u put a catridge in mag
Does it come out the top valve or the second co2 piercing needle?
@@RWMAirgunsmithing with mine wen I fill the first one up on the left the air goes out of the right side so I have to put a used co2 in the right one tighten it up and then do the left side so no air leaks so basically im jus having one co2 in it instead of 2 and I dont know how to fix that do you know ?
@@zachade9998 you probably need to tighten the ring seating the piercing needle and seal on the "second" co2 sĺot. Follow the steps in the video, it might just need to be snugged into place.
What video do i watch if i want to change the cover on my mag
You mean the black plastic pieces? there are only 3 screws holding them in, check out my disassembly and reassembly videos, I go over it piece by piece and show what to expect underneath the covers.
When i take the screws out it doesnt come off
@@Walmartbag142 hmm, that is odd, the 2 top ones screw both halves together and the bottom screws into the metal body of the mag.
Technically there isn't anything else holding them together, was the magazine ever dropped or something?
No i cant get the two screws out i havethe same screw driver and they wont come out
@@Walmartbag142 if the screw turns but doesn't come out it sounds like the plastic threads are stripped. Did you shine a light to make sure the screw head is not stripped? And also, that is a tight fit, are you using precision screwdrivers?
I have an sbr and I’m guessing that’s why I got this as a recommended video but, you have how many mags? God damn dude they are like $50 per lmao you got the same amount in magazine cost as I have in my gun
xD Ill take that as a compliment heheh, you should see my pile of pistol mags lol
Thank you for the video! The rifle, although problematic, is a lot of fun! It’s a pity that in my country, due to political issues, it is now impossible to buy stores, even order from Ebay (delivery will cost the same as the cost of the store itself)
No wayyy! Hope you bought an extra for spare parts hehe xD.
And yeah, this is my favorite, love how they managed to fit 99% of the real manual of arms into this replica.
@@RWMAirgunsmithing Alas, I didn’t have time :( do you know about the mod that supposedly increases the speed of the ball - it involves removing the mesh under the rubber seal of the first CO2?
@@MrEvENGED I can see how that screen could impede flow from the CO2. Although if you're comfortable taking it apart I would recommend keeping it clean every couple thousand rounds. I am curious though, might test it out over the chrony.
There shouldn't be many downsides except you will wind up with CO2 manufacturers gunk inside your valve and barrel which would require a cleaning every now and again.
@@RWMAirgunsmithing yes, it would be interesting to measure it through a chronograph! I agree about cleaning, but I think this procedure is generally useful for any pneumatic :)
Have you ever tried to mod one to fire pellets ?
Valid question! I've seen people talk about it in forums and the tinkerer in me has always went down the rabbit hole... but...
The problem is : bb's are spherical and random orientation of 25 bbs in a mag does not matter. So manufacturers can capitalize on that and make awesome replicas with drop free mags.
These mags could definitely shoot pellets but you would have to tinker with the bb follower and guide and the entire bb channel and swap barrels to have some barrel rifling and most definitely would need to shim and angle everything at each step. Edit : not to mention the technicality of loading the mag after all these mods.
It would definitely be an amazing tinkering feat that comes with bragging rights... but in reality you can purchase a hpa full auto pellet shooter except would not be a "AR replica".
My advice would be to get the most out of these amazing AR replicas (for training and plinking these guys are accurate out to 50-60ft) and if you want better ballistics then you should definitely look into buying a real pellet airgun.
Hey bro got any pointers if I wanted to hpa tank this?
I am eyeballing the bulk-fill adapter sold by pyramydair. From everything I can see they made it for the crosman magazine. Just need to buy all the accessories.

@@RWMAirgunsmithing yup more a less what I was looking at too buddy. I'm thinking about it :) would be cool
@@RWMAirgunsmithing cause the magazine replaced is 60 bucks but I could just go a step further n get mass air tank lol
@@bradfletcher6826 not to mention more consistent velocities and if you have a regulator you can dial in the perfect pressure xD
I have a couple of optics I wish I could zero without worrying about the thermal aspect of co2.
@@RWMAirgunsmithing I just made a slamfire 22 from a paintball gun so I'm looking to modify my next project lol
you and Rumble Canada need to get together.
Hehe, with the new gun laws in Canada maybe plinking will blow up and we can go viral xD
Where do we order a new clip
I would suggest just googling "spare crosman magazine" maybe add your state or province.
And of course, amazon, , ebay, airgun depot, replicaairguns, pyramidair, crosman.... just google it an pick best price or closest store.
Amazon has them for sale
you can port the Plug in the Valuve with a dremel.
the inside bore with the big green o'ring type seal? yeah definitely, you could probably replace the green seal with a thicker o'ring too if its a last ditch effort.
@@RWMAirgunsmithing but if you have the Can. Ver. that casing behind the seal is too thin they did that on Purpose it will crack BUT! you can Reinforce the inside with Liqiud Metal Epoxy just apply a thin coat to it and let dry
also be damm sure to keep outter edges clean when you do it.
@@joseglenn4435 Can. as in Canadian? Not entirely sure that is a thing.. the boxes in the US also state 430fps and they all work off the same magazine.
Liquid epoxy sounds great but I think at that point you really got a bad mag out of tolerances.
you mean yes you can i got 723 fps but but 3 mags. max but well worth it.
@@joseglenn20 75 rounds at 700+ fps does sound like a lot of fun xD that would destroy my backstop though hehe, I hope to have the range to test at distance one day!
So the story here short version. Send it to crosman lol
Lol xD if it is brand new and you know exactly when you will get the replacement and if you aren't losing a plinking session!!! xD (cant lose those plinking sessions!)
I wouldnt bother with a leaky frame or valve either hehe, but the internal "jammed" check valve is an easy fix.
Actually if you get BBs stuck in the spring just remove the spring from the magazine and the BBs will come out do NOT try to use a pick and get them out without removing the spring you will destroy the spring but if you do mess the spring up crosman will send you one for free...
Totally agree, first option when possible should be the spring removal technique.
@RWM Airgunsmithing love all your videos I did the shim mod and my property has been taken over by pine squirrels well there's a new sheriff in town bagged my 1st one yesterday head shot and the bb went in...
@@jonathanulery1610 thanks for feedback! xD don't really have the flexibility of shooting outdoors atm, wish I could take advantage of some of these power mods hehe
Do they make mags for more bbs
Yeah, they call it the quick reload mag, holds 250bb. I never use it though, I prefer loading 2 mags and letting the CO2 rest
@RWMAirgunsmithing i found the mag on amazon understand the c02 cart resting amd does it fit well with this crosman ar with 2 c02 cart mag system
@RWMAirgunsmithing where can i find mag that doesnt jam like that 250 round bb mag all i can find is for airsoft thats like 45-50 round if not a drum thats mechanically sound
@@bulletproofpinata2328 there are only those 2 models of magazines and there is no airsoft version. I dont have any issues with my mags, but this is why i made the video so i can help others. I treat these airguns with the same manual of arms as a real AR and have no issues plinking. These guys are more on the "replica for training" side of the spectrum, they operate 99.9% like a real AR as far as the user is concerned.
@RWMAirgunsmithing yea i have the bb full atuo gun for these mags but cannot find any type of mag that holds more then 25 thats compatible with this crosman airgun ar
Broken spring in mag
Goto Rumble Canada dude get power mods 800 fps.
Ya crazy stuff xD. Dont forget to watch his upload about how he consistently breaks all his crosman's internals. Hehe
@@RWMAirgunsmithing I know i'm learning from him. but how else can you learn.
@@joseglenn20 yes all information is good, it just takes experience to categorize it. Rumble canada is amazing but his mods and fixes only apply to modified crosmans, they do not relate to stock crosmans at all.
@@RWMAirgunsmithing so true but the bug bit me .
I'll be going down the path of Power mods.
i'd better ask the boss for a raise.
@@joseglenn20 Power mods can be great if you have the range and backstop for it. I am planning on rigging a mag for HPA with a regulator so I can zero all my optics with no co2 thermal influence.
19:56 why would you do this if you don’t have any air leaking to begin with, like you say?? Makes zero sense
Do what? Ensure the mechanism cycles completely through both co2 during use? Yeah, who would want that xD
why is it when I click on gun stuff the picture never comes on, but when i click on dumb shit it connect real fast, c'mon you tube stop the shit
Make sure all your apps are up to date, if you are on PC maybe a good clean up of stored data might help xD I dont represent TH-cam but maybe that will help hehe.
Thanks for bitching on TH-cam because my video didn't pop up fast enough! xD I take it as a compliment!
I'm not sure if I'm surprised or not that Crosman hasn't updated this garbage magazine design. Namingly, the pain of reloading the f***ing thing. Surprising because this overall platform system could be THE design to recommend to anyone except for the magazine. Not-surprising because that's the apparent theme of air guns: "almost good enough". Perpetually almost good enough. For decades.
Yeah, definitely not like the real thing xD Pretty much all the replica airguns have their issues, but you trade some performance for realistic handling.
It's frustrating, but hey I still play the game. I really like the format these use where you can interchange uppers and lowers. If they made an entire line like this, it would be awesome to be able to swap in different calibers or maybe a rifled barrel with mags that push diablo pellets up. Or something, the ability for innovation here seems massive.
I got mine on HPA and am planning at some point to convert a 6mm drum to feed somehow, was thinking about using the top of a standard DPMS mag and finding a way to get the drum to feed up the usual BB stack.
Wish in one hand, couch potato in the other. lol
The barrel on my m4a1 build is a crosman 1077 rifled barrel. I have a video in the works for replacing the stock crosman barrel. (Still shooting bbs though hehe).
Its true all their models are almost all identical but I enjoy the fact they are soooooo milspec you can take it apart and tinker with it.
Good luck with the 6mm drum mag xD
Why does a consumer have to fix a faulty design?! Wth?! It should work out of the box!!!! I’ve purchased 5 cartridges and none of them work correctly. It’ll drain the first co2 but it never utilizes the second co2 cartridge. The second co2 is always never engaged and is wasted. Just fix this f’n thing. Thanks for taking my money DPMS.
Yeah totally agree the quality control is not up to par at all. It sounds like the check valve is constricted on your mags, but remember you never need to overtighten your co2, on this magazine if you overtighten the second slot co2 you will compress the check valve.
If you need help performing the fixes in my videos lemme know!
Nah you right bro I feel like if u gonna sell people stuff make sure it works I paid too much for this bb gun but it's is fun to shoot sometimes tho I got pull the trigger and it sets everything off like it should but the bbs don't fly they just stay in da mag
@@antonplayzgamez631 how does the hole on the rubber "chamber" part look? If its mangled on the bottom section it means the mag is not seating properly all the way in and the hole on the mag is slightly lower than the hole on the rubber barrel "chamber".
Very rarely but it happens, the magnet in the mag at the top of the bb channel shatters or is missing, making the bb rest higher than the hole in the mag. Need to at least put a drop of crazy glue and let it dry to make the bb line up with the hole.
I know you're trying your best buddy but maybe start watching your own videos and that's what I used to do you learn from it and you also learn what not to do and what to do more of keep up the good work and I'm still trying to figure out if you're giving tips or what but I guess this is a video on if your clip leaks CO2? I thought it was like tips and tricks or something it said I don't know
Thanks for feedback, but just curious... do you have problems with your magazine and this did not solve it?
If you actually own a crosman and have problems with your mag I would love to help..... buddy.
Very hard to watch
Painful
Please elaborate...
so moral of the story that thing is crap?
Hehe xD I wouldn't say crap, but there are a lot of comments out there about widely varying performance issues. The most common problem on the mags is with the "first/second" co2 check valve, it just takes the tiniest adjustment on the rings and that will usually get these running just fine.
This gun sucks ass!!’
Is that how kids call awesome things now? Hehe, thanks for that suck ass comment! 😜
I can maybe help you get to love it! What is yours not doing that you think it is supposed to do?
Sounds like you have horrible luck with airguns. Maybe retire.
