No shit, Ive run phos bcg from the get go…… I also only want carpenter steel no 9310 substitutes ever……. Don’t get caught up in this gucci bullshit that most do!
Everything you said was right on the money.I have Colt rifles 2 m4a1socoms and a Geissele urg-i thats basically a Colt too.All three are milspec and 100% reliable.I like companys that don't take shortcuts and Sons of Liberty seems to be outstanding.Because of your knowledge and matter of fact style of speaking I will be buying a Sons of Liberty rifle.I now have confidence that it will run 100% reliably.
I use C158 and 9310 bcgs and never had a problem with either one. I also use a little weapon shield gun grease on my bcgs. It doesn't evaporate off or burn off very easily and stays where you put it. I've used it after its been on the gun for 5 years in storage and it still does the job.
There is also the correct 3 bore sizes in the bolt carrier and having proper machining that meets TDP spec. Every SOLGW bolt carrier I have put on my bench has passed with flying colors..SOLGW puts out an outstanding product..
I'm glad I bought a couple if SOLGW bcg's a couple of years ago when they were on sale. I love my SOLGW rifle and seriously doubt if I will ever need those bcg's, but I'm glad to have them, anyway. This guy knows what he's about. Thanks, Mike.
Ok, I knew that some bolt carriers are better the others, I didn't know how good yours are. I'm a tool and Die- moldmaker. Those specs on your bolt are damn sexy! I just got a bolt today from a competitor in Wisconsin, because of its properties. I'm starting to take notice of quality and commitment. Thanks for sharing.
You are 110% Correct very few people know what Milspec is or isn't. Love it when I see NITRIDE BCG and says Milspec. I'm a sucker for TDP Colt M16 BCG / Bolt. Colt and LMT are the only ones I've never had an issue with . I do need to try one of SOLGW M16 BCG / Bolts. Colt gold spring is my go too for sure . I'd imagine yours is probably the exact same or better.
Appreciate the awesome content! The best rifle companies use the ole tried and true and follow the specs to a tee. I look forward to getting my hands on one of your all’s rifles
yup, Mike is laying down what SHOULD be common knowledge about a BCG. I use SOLGW and SIonics BCGs for any rifle I consider a "duty" grade rifle (sure, I have no problem grabbing a $70 toolcraft BCG when I'm putting together an Aero or PSA fun gun. I'm not so worried about the small chance of premature failure there).
As My time in the military has progressed and my studying of those specifications has progressed I have learned that “milspec” is not what most people think. Mil-Specis commonly confused with poor maintenance and repair. Mil-spec is not the common problem it’s components that have exceeded there intended life cycle.
Runs like a machine in my builds, just got another in for the next setup. So excited got 8" M76 handguard and barrel nut coming in next week, and 9" barrel just shipped paired with my NOX-300. Mike your team are some of the finest patriots and appreciate you all! Stay Strong, Stay Safe *Need a Soul Snatcher Stripped when store opens again.
Dude is a genius. He sells mil spec gear at Geissele prices. They don't do anything but above and beyond. They just aren't trash. It's like asking for a promotion because you do your job correctly. The fact is the prices are high because he can't manufacture at a high enough rate. I think people see this and that is why their prices are sliding down.
First ar was a PSA... decent rifle for the price honestly but I just got a BCM upper and built a new lower, it's awesome and if I do another ar I like it to be a SOLGW! Would have loved to build my new lower with a solgw receiver but pickings are slim these days!
Ok bro been watching these video and you sold me. Been building guns for 17 years and your knowledge is amazing! I am sold if I could find your guns in stock I would buy now for duty use!
Just how you conduct yourself and how it product speak for them self I wish u had stuff in stock so I could support your business!!!! U guys are badass
Glad to see my M&P15 Sport 2 bolt is made from 158 Carpenter, magnetic particle inspected, and is phosphate coated…I know there are far more expensive rifles but it’s been a great one for me this far. I’ll just focus on upgrading the trigger now..
Isn’t the viability of the magnetic particle test based on doing the high pressure test first? You’re looking for the particles to adhere to imperfections or failure points once magnetism is applied to the medium. Why would there be apparent cracks before the HPT?? Isn’t one redundant without the other??
JT I don’t worry because it’s a SOLGW bcg they have the rebellious stripes flag etched on their BCG. It has 9 stripes 5 red 4 white stripes each representing the loyal 9. en.m.wikipedia.org/wiki/Loyal_Nine
I bought your guys v2 combat chf barrel and the damn feed ramps have a decent edge enough so its running my bullets kinda shitty seeing what I paid for it
9310 is used in m240 and m249 bolts and is just fine, a 9310 bolt heat treated right beats a 158 bolt with a mediocre heat treat every time. And we see sharps putting out bolts in s7 tool steel which is one of the strongest tool steels out there and barret has been using s7 for 50 BMG bolts for a long time with great success, again it matters how it's heat treated. Also you said 9310 bolts aren't HP tested but we're seeing Aero precision, PSA, and other companies doing those tests on 9310 bolts so I wonder if they have any data on what percentage fail. Now as far as c158 bolts go I would trust a solgw one more than most but just because something was the original formula (from the 50s and 60s) doesn't mean it's still the best as metals and heat treatments and coatings get more advanced. Remember stoner originally wanted a chrome BCG as it is more slippery than phosphate, and while phosphate "holds lube" better it better hold lube because it is a very rough coating and needs more lube than chrome or nickel boron or DLC. I agree coatings should be the last thing considered after materials, tolerances, and hpt/mp but modern coatings make these guns able to run far more rounds between cleanings or reapplying lube. My nickel boron bcg from stag arms is my favorite bcg, it will run with zero lube though I still lube it and will run dirty as hell better than any phosphate bcg I own.
Nickel boron is the absolute worst bcg coating and seriously any time you see a bolt that failed prematurely it’s always 9310. Check school of the American rifle out on TH-cam if you actually want to learn something about bolt carrier groups
@@douglasm3310 i have i've watched just about all of their videos, it depends on who makes it. there are nickel boron ones that failed their checks and ones that passed every single check. and idk where you get that 9310 fails prematurely more often, that has not been my experience at all. 9310 is used to make bolts for m249's, m240's, and ar's and has more tensile strength than carpenter 158. the best bolt on the market is probably the geissele one that is carpenter 158 that he worked with carpenter steels to make with less impurities and it's a 100% forged bolt. but that bolt costs a ton, right now my two main rifles that have the most rounds on them have a sharps s7 tool steel bolt and a 9310 nickel boron one, the 9310 is approaching 9,000 rounds and is on it's 2nd sprinco extractor spring and second extractor, and my sharps bolt is in a rifle that i just re-barreled at about 27,000 rounds that bolt has been used since about the 7,000 round mark when my carpenter 158 mil spec bcm bolt broke while firing. take with that what you will, i've been building and shooting the hell out of these things since i was 8 years old and in my experience a good nickel boron bcg allows it to run far longer between cleanings and with more dirt and less oil, it will run without any oil but it's always better to keep it oiled obviously. i don't really need to clean my nickel boron ones but i do because it's an opportunity to see everything and spot problems before they arise
@@bobbyc2768Like Chad (SOTAR) mentioned, if the tolerances & specs before the nitride is applied you should be good. Still hunting down somebody that makes a correct spec chrome internals nitrided bcg.
@@CarlPapa88 i wonder how brownell's bcgs are, obviously we can't know unless they're gauged like chad does but a few years ago a friend of mine wanted a nickel boron one (which companies tend to screw up as we've seen on this channel leading to failures or just sloppy tolerances) and i gifted him one from Brownell's for a really good price, 3 years later he has roughly 16k rounds on his, the original bolt is still going although on my advice he got a spare bolt that's been live fired to test with a couple hundred rounds and headspaces correctly for when that bolt does eventually need replacing. never an issue ever with that bcg from brownells, never so much as a hiccup. i've been keeping an eye out to see if one of them ever came across chad's desk to be gauged but haven't seen one. a lot of the same issues a manufacturer can run into with nitride they can run into with NB as far as dimensions go. obviously there's no way to make sure everything is in spec without having the gauges chad uses, but i can say the thing runs perfectly for that many rounds and we were both pleasantly surprised as they were priced pretty well compared to other NB bcg's especially failzero which we've seen fail on a few of chad's videos.
I purchased your bolt carrier and put inside my BCM upper. Ran fine until it ran into some hornandy 62 grain ball Ammo. I put the BCM bcg back on no problem. I believe your bcg are high quality also colts bcg could not fire that round reliably either.
Interesting, I have paired my SOLGW bcg and barrel to a BCM upper, as well. Gonna have to check this for my self, as soon as my other parts get in to complete this build..
@@willieluv Did you check firing pin protrusion on the bolts? Seems odd that the BCM would give a good primer strike and the others wouldn't, considering that hammer motion is the same. Not trying to pester you, just curious about things like this.
l 800X no problem I did not all I know is the BCM bolt performs no matter what. Same thing happened with my colt bcg as well. I use hornandy 62 grain as a test because the ammo is no good. Out of a 150 round box at least 20 of them won’t fire. Also Daniel defense bcg same thing. BCM was the only one that fires all ammo in the box no problems on first strike. This is unscientific I did not check bolts on why it just is.
Here is a really long geek question. First, I knew, or thought I knew, that there were different types of steel used in the construction of the bolt carrier group. But seeing your parts list really put into perspective. Does the differing steels of the carrier 8620 and gas key 4130 come in to play when they heat up? I guess as one steel becomes heated and expands at a different rate than other type of steel, could that create an issue that over/under gas's the BCG? Now if this does not play an issue with the SOLGW bolts, and other high quality bolts, could this be an issue that shows its ugly head on low end builds that use cheaper steels?
Question. Could you take one of the SOLGW BCGs and use it in any 5.56 rifle by any manufacturer (for example: Aero Precision, BCM, Colt, Daniel Defense, FN, PSA, Ruger, or Smith and Wesson)?
I'm definitely going to buy one of your BCG's. The springs sold me lol. I've been running an HM Defense HMB BCG and they seem to be solid with their cam pin socket instead of hole. What's your experience or take with BCG's breaking at the cam pin hole natural weak point? Great video/information thank you.
I bought a DPMS Oracle and NOTHING is Mil Spec on the entire rifle. I since have changed that. It is still not MIL Spec but it is a runner all the same.
What solvent do you guys recommend using when cleaning your Bcg's? I try my best to not use any kind of scraping tools or metal brushes to interfere with removing tolerances but with the phosphate coating it's murder trying to clean the bolt tail. Even soaking with hoppes I still have to aggressively scrub and there's still a nice layer of carbon...
When are you guys getting more in stock? Been wanting one of yours for sometime, I have great bcg's in all my rifles. I need one of yours to have in my safe. I love the idea how you build your rifles, I've always been behind that same concept!!!!! Love your videos thank you so much as a owner.
Not all LPKs are the same, in fact you can tell the difference between a SOLGW kit and many others just by the weight and fit/finish. I have the notes somewhere from the armorers class I took where Mike taught, but they don't cut corners by using cheaper metals in anything, especially in their LPKs. Some companies use a cheaper metal in their LPKs because it's a corner they decide to cut to maximize profit, and for the casual shooter who is only putting at best a few hundred rounds a year through their rifle will probably never notice. I have yet to see a SOLGW bolt catch break, but I've seen plenty of others break, especially SI parts.
@@robertharper3754 Can you safely and reliably use SOLGW parts like the BCG in non SOLGW guns (ex Aero, BCM, Colt, Daniel Defense, FN, PSA, Ruger, or S&W)?
@@FinalLugiaGuardian, yes, as long as the bolt headspaces correctly you're good to go. Granted, the chances of getting a bolt and barrel that is going to fail headspace in any AR15 is pretty slim but when I build a gun I always check to make sure the headspace is good. SOLGW BCGs and all their other parts are for sure in mil spec tolerances and usually much better/tighter tolerances. I've never had any real issue when using their parts, but there is a thing called tolerance stacking, where you can have all in spec parts but all the small variations on dimensions of the parts add up to cause an issue. I've seen it most with the lower receiver and it's extension, (the buffer tube), when the variation in dimensions can add up to there being not enough room for the when the BCG comes back and it can smack your lower. With the buffer and spring installed take your BCG and push it in as far as it will go, the BCG shouldn't touch the lower and there should be enough room for two quarters stacked together to fit between the BCG and the lower. If there is not enough room for the quarters then take the buffer and spring out and place a quarter in the buffer tube and test again. You should really look up School of the American Rifle, he has a TON of videos on youtube and instagram and he has his own forum thing that is worth every penny, (it isn't much), to join. Lots of good people and TONS of knowledge there, and they'll answer any question and help anyone out with any build problems. Hope this helps!
Used both 9310 and 158. I think bolts are just like most things the better specs, tolerances and quality control are what matters. Most people that say 158 Carpenter nothing usually follow it up with military uses it but doesn’t understand the history behind why. If you didn’t know it is because the technology back in the 60s 158 Carpenter was the better of the two. Now technology has progressed and 9310 specs are better, if it’s from a reputable company like Aero. But hey this guys got to sell his product so no bias from him ;)
I assemble my own BCG set up with different industry parts. Carrier from one place bolt from another springs ect.. no detail over looked❤, i didn’t come up with this formula overnight but decades and decades and decades(oh yeah i’m an old fart) of trial and error. along with a great buffer and trigger/barrel
hello, I just got my first ar-15 and I purchased a Springfield saint. It seems like a nice rifle but what would be an internal upgrade to that gun to make it more reliable? Im not sure what kind of gun this is, is it military ready, would it be reliable enough to do so or is it more of a budget rifle?
I'd say check the springfield website and read their specs. The Saint is a entry rifle but on the higher end of entry rifles. I'd make sure the rifle isn't over or under Gased (check the ejection pattern). Most importantly you need to shoot the rifle to see if their are any wear issues. If your looking for an internal upgrade a BCG from BCM or SOLGW would be a great choice.
If the cryptic coating bcg weren't $300 and the specs were similar or better I don't see why someone wouldn't choose the bcg. For some who shoot suppressed and have cans with a lot of back pressure, burning off or drying out a phosphate coated bolt can be a pita to clean. This is not to say that a CC bolt isn't but it is a lot easier by comparison. I wouldn't hesitate to purchase a DD, BCM, SOLGW bcg, but if my cleaning schedule is more robust than yours perhaps no matter what I choose I'll likely want it to be easier to clean/maintain in the long run. If all I have to do is take a rag or a paper towel and wipe down the bcg and re-lube, I'd say that short amount of time is worth the added cost so long as performance isn't sacrificed.
A great description, I would love to see a video about all your barrel specs. I have seen speculation that they are B.A. private label. I honestly dont care who makes them, I know they run well and have a lifetime warranty. I like the Faxon gunner profile, wondering if you have anything that skinny?
geebeaux BA makes our barrels to OUR specs. Our porting and everyone is HP/MPI not batch tested. Our warrant is simple.. shoot it out and we’ll replace it. Go check out the warrant video..

Would you consider a video on your standard carpenter bolt vs your NP3 BCG? I'd love to hear your decision making process in chosing between them.
NP3 is just a coating.
Here is a really long geek question. First, I knew, or thought I knew, that there were different types of steel used in the construction of the bolt carrier group. But seeing your parts list really put into perspective. Does the differing steels of the carrier 8620 and gas key 4130 come in to play when they heat up? I guess as one steel becomes heated and expands at a different rate than other type of steel, could that create an issue that over/under gas's the BCG? Now if this does not play an issue with the SOLGW bolts, and other high quality bolts, could this be an issue that shows its ugly head on low end builds that use cheaper steels?
Question. Could you take one of the SOLGW BCGs and use it in any 5.56 rifle by any manufacturer (for example: Aero Precision, BCM, Colt, Daniel Defense, FN, PSA, Ruger, or Smith and Wesson)?
Yes!
Damn.... And I thought I geeked out on the specs. How can I buy this man a beer? (No, I don't need to be there. lol)
Is Microbest contracted to make your BCG?
I believe so
That’s who makes BCM and SOLGW
My go to for bcgs
👍👍👍👍
BCM recommends the o-ring in a bolt on suppressed builds. What are your thoughts on that?
What lubricant should i be using?
bored at work. sweet video
Just bought my first SOLGW product, this BCG
GREAT VIDEO MIKE!!! 💪🏼🇺🇸
So these will hold up against the battering from a pistol length 7.0” 5.56?
I'm definitely going to buy one of your BCG's. The springs sold me lol. I've been running an HM Defense HMB BCG and they seem to be solid with their cam pin socket instead of hole. What's your experience or take with BCG's breaking at the cam pin hole natural weak point? Great video/information thank you.
I bought a DPMS Oracle and NOTHING is Mil Spec on the entire rifle. I since have changed that. It is still not MIL Spec but it is a runner all the same.
I love the inside info! Just out of curiosity why are ar bolts not forged? Thanks.
What solvent do you guys recommend using when cleaning your Bcg's? I try my best to not use any kind of scraping tools or metal brushes to interfere with removing tolerances but with the phosphate coating it's murder trying to clean the bolt tail. Even soaking with hoppes I still have to aggressively scrub and there's still a nice layer of carbon...
Thoughts on using torque wrench for barrel nut, or just.. yeah that's about right. I've done it both ways.
When are you guys getting more in stock? Been wanting one of yours for sometime, I have great bcg's in all my rifles. I need one of yours to have in my safe. I love the idea how you build your rifles, I've always been behind that same concept!!!!! Love your videos thank you so much as a owner.
think they moving their website
Mike, could you do a video on your lower parts kit? Are all LPKs the same? What makes yours different? Would be curious to know.
Not all LPKs are the same, in fact you can tell the difference between a SOLGW kit and many others just by the weight and fit/finish. I have the notes somewhere from the armorers class I took where Mike taught, but they don't cut corners by using cheaper metals in anything, especially in their LPKs. Some companies use a cheaper metal in their LPKs because it's a corner they decide to cut to maximize profit, and for the casual shooter who is only putting at best a few hundred rounds a year through their rifle will probably never notice. I have yet to see a SOLGW bolt catch break, but I've seen plenty of others break, especially SI parts.
@@robertharper3754 Can you safely and reliably use SOLGW parts like the BCG in non SOLGW guns (ex Aero, BCM, Colt, Daniel Defense, FN, PSA, Ruger, or S&W)?
@@FinalLugiaGuardian, yes, as long as the bolt headspaces correctly you're good to go. Granted, the chances of getting a bolt and barrel that is going to fail headspace in any AR15 is pretty slim but when I build a gun I always check to make sure the headspace is good.
SOLGW BCGs and all their other parts are for sure in mil spec tolerances and usually much better/tighter tolerances. I've never had any real issue when using their parts, but there is a thing called tolerance stacking, where you can have all in spec parts but all the small variations on dimensions of the parts add up to cause an issue. I've seen it most with the lower receiver and it's extension, (the buffer tube), when the variation in dimensions can add up to there being not enough room for the when the BCG comes back and it can smack your lower. With the buffer and spring installed take your BCG and push it in as far as it will go, the BCG shouldn't touch the lower and there should be enough room for two quarters stacked together to fit between the BCG and the lower. If there is not enough room for the quarters then take the buffer and spring out and place a quarter in the buffer tube and test again.
You should really look up School of the American Rifle, he has a TON of videos on youtube and instagram and he has his own forum thing that is worth every penny, (it isn't much), to join. Lots of good people and TONS of knowledge there, and they'll answer any question and help anyone out with any build problems.
Hope this helps!
Why does my brand new BCG look like it's had many rounds fire with it?
Because we test fire each BCG in a machine gun after assembly. Start at 4:18

Speaking of springs. Is the Geissele Super 42 buffer spring over rated?
No
legit
What's your thoughts on Geissele's use of Carpenter 158+ for their bolts?
Used both 9310 and 158. I think bolts are just like most things the better specs, tolerances and quality control are what matters. Most people that say 158 Carpenter nothing usually follow it up with military uses it but doesn’t understand the history behind why. If you didn’t know it is because the technology back in the 60s 158 Carpenter was the better of the two. Now technology has progressed and 9310 specs are better, if it’s from a reputable company like Aero.
But hey this guys got to sell his product so no bias from him ;)
Most companies can not afford to do things true "mil-spec." Not meeting equivalent testing requirements.
Can y’all make a video of your cleaning and oiling process please, if y’all send this reply so I know I Was heard thanks!!!
I assemble my own BCG set up with different industry parts. Carrier from one place bolt from another springs ect.. no detail over looked❤, i didn’t come up with this formula overnight but decades and decades and decades(oh yeah i’m an old fart) of trial and error. along with a great buffer and trigger/barrel
hello, I just got my first ar-15 and I purchased a Springfield saint. It seems like a nice rifle but what would be an internal upgrade to that gun to make it more reliable? Im not sure what kind of gun this is, is it military ready, would it be reliable enough to do so or is it more of a budget rifle?
I'd say check the springfield website and read their specs. The Saint is a entry rifle but on the higher end of entry rifles. I'd make sure the rifle isn't over or under Gased (check the ejection pattern). Most importantly you need to shoot the rifle to see if their are any wear issues. If your looking for an internal upgrade a BCG from BCM or SOLGW would be a great choice.
Dislikes must be the dudes running $300 Toolcraft bolts from cryptic coating. DD, BCM, SOLGW. Why buy anything else.
If the cryptic coating bcg weren't $300 and the specs were similar or better I don't see why someone wouldn't choose the bcg. For some who shoot suppressed and have cans with a lot of back pressure, burning off or drying out a phosphate coated bolt can be a pita to clean. This is not to say that a CC bolt isn't but it is a lot easier by comparison.
I wouldn't hesitate to purchase a DD, BCM, SOLGW bcg, but if my cleaning schedule is more robust than yours perhaps no matter what I choose I'll likely want it to be easier to clean/maintain in the long run. If all I have to do is take a rag or a paper towel and wipe down the bcg and re-lube, I'd say that short amount of time is worth the added cost so long as performance isn't sacrificed.
@J Hof Sionics makes real good stuff.
Why did you guys choose to make yours more like a standard mil spec BCG instead of the LMT style full auto enhanced?
"gun shots has entered the chat*
They dont even list BCG's on their website so where can i buy one?
Primary Arms
What's the name of the spring and who can I get one
Springco extractor kit from Sprinco USA
Do these bolts need to be ran more wet than usual?
No
Ddaaammmnnn! Is that shit in stock!!!?
What's his number? How can I get one?? Spring
What material spec is the carrier?
capt_conrad it’s listed one the video and the video description
LOOK!!! 10 competitors came to the video to give it a thumbs down!! (Or just people that are sad to learn this stuff after the fact)
The original formula is a chrome bcg.
My wife asked me why my SOLGW M76 was so expensive...
I told her it's "Mil-Spec"... 😆
A great description, I would love to see a video about all your barrel specs. I have seen speculation that they are B.A. private label. I honestly dont care who makes them, I know they run well and have a lifetime warranty. I like the Faxon gunner profile, wondering if you have anything that skinny?
geebeaux BA makes our barrels to OUR specs. Our porting and everyone is HP/MPI not batch tested. Our warrant is simple.. shoot it out and we’ll replace it. Go check out the warrant video..
May i have a job?
When the market calms down I think I'll grab an 11.5 upper from you alls.
Who manufactures your BCG? is it ToolCraft ?
Microbest.
