Just bought a used mp9 myself. Owner sold it because it couldn't fire more than 10 shots. Turns out the cup seal was ripped, ordered the Lees Presicion piston head now it runs pretty good other than the fact that sometimes the bolt doesn't come all the way forward, which doesn't activate the trigger and a new shot can not be fired. But thanks to your solution with the extra spring this problem also got solved! Thanks
After 7 years as mp9 KSC owner....I would never sell it, and by the way I had the same issues as you shown in the video. But finally, a very good f....ing video on the mp9 !!! 🤟
that tip involving moving the outer barrel, honestly, has just saved me literally fucking hours of grief. every time i've taken it apart i've had trouble inserting that bloody pin! THANK YOU
Aap 01 rocks. It's good out of the box with .36 gram bbs. You need a 138mm crazy jet or 6.03 tb gbb barrel, a 50 degree maple leaf autobot and the hadron I key, the suppressor adapter (to cover the extra barrel length with a suppressor). With those components you can rock .48s out to as much or more than 120ft. Word of caution though...get the glock 18c extended mag or you will mag dump a standard mag in 2 seconds on full auto.
Thanks for this info! I run the mp9 with a cqb bolt on hpa (semi auto mainly) and the recoil spring was not strong enough. Your vid helped me a lot! Best tech on TH-cam for sure
I was getting tempted to pick up an MP9 while watching this right up until you pulled out the TMPs at the end and I remembered which was the better looking gun.
Great video 🤟🤟👌👌👌👍👍👍your colorway looks epic!!! Would like to powdercoat or paint it the same Could you tell me the name or type of color? Greets from berlin
I can for sure agree with you that the MP9 with it’s correct integral grip is the only way to run an MP9. It feels wrong with the rail tbh lol. This’ll be very helpful should I invest into an MP9 myself one day.
May i know did you test fire in this video using 134a or green gas? Also I thought there are two versions of the MP9s, one with KSC using 134a gas and a KWA that can use green gas properly. Keep up the good work and thanks for your videos
I bought this gun used a few months ago as my first airsoft gun. Tell you what, it's a headache with all the issues and upgrades needed, but this fucker is a blast to play with. It's like an abusive relationship where the sex is fucking amazing.
I want one. It's impossible to find right now. Can't find one, spare parts and I would like to give it to you for check and custom one day (in case...)
Hey there I was just wondering with all your experience working with Airsoft guns, what AEG would you recommend as the best for a second or third gun? (Not fussy about price just want to know what gun you would recommend if price wasn't a issue)
Ok, i have an idea. We all know how Negative love VFC and Gate Titans, so i think Negative should do a review /his impressions on Novritsch SR15. Thumbs up if you like the idea ;)
Going to drop some dosh on those Lee's next month, and I think I have a few extra mag springs lying around... That's probably going to make a world of difference. Now if I can JUST figure out why it constantly overhops everything on green gas I'll be golden.
@@opairsoft8100 Ahhh that might definitely be it. What would you recommend then? Strict fps/joule rules here means I can't go above 2.0 in green gas PSI wise.
this toy did give me allot of problems, usualy the disconnector brake, it's so hardcore maintenance ... Wii Tech and RA-tech used to build aftermarket parts for this toy ASG(KWA) and KSC one
Different camera angles! I was also going to get my head down but this appeared so here we are. Gotta say I haven't seen that kind of fine attention to detail anywhere else........I would still never buy one, but if I did I now know what the fuck is up. Noice.
Nice video as always. The MP9 is a dream to play with as long as it works. I have heard people claim that loading the thing without locking the bolt back risk breaking to loading arm. Any guess if that may be true?
@@ritzcar9011 i don't know how common it is but it had that problem when I bought mine second hand. The catch works just like on a gbb pistol but the catch is must harder than the bolt and it is sharp, so it wears down the "ledge" which it catches on for every time you release the bolt. I tried rounding off the surface on the catch and I filed a new ledge on the bolt, but it worn down again. My MP9 is disassembled for the moment but I am planning on adding epoxy where the bolt meets the bolt catch so it hopefully does not wear down.
@@Thahamster Every gas gun has that issue if you 100% load the mag - always leave 2 bb's of space so that you can get a mag in without damaging the nozzle.
i dont know if i have just been lucky but the only problem i have ever had with my mp9a1 is if im to agressive with firering either in semi or full auto it sometimes gets to cold so the firemechanism locks and just goes full auto with out touching the triggger. but thats usuall after dumping 2 or 3 mags i think thats okay considering im not taking to good care of it. its just a fun thing until it has a serious problem
4 ปีที่แล้ว
I had the KSC version many moons ago. I don't even know why I sold it. Wanted to try something else, I guess...
@@NegativeAirsoftTech sorry i love it being so small, perfect for cqb. But what about the internals? I would love to send it to you and say Just make it better but i live in a Belgium So i dont think its possible 😞
Finally found a used one for a good price and seems to be in good condition (lol we’ll fuckin see) tan which isn’t my first choice but is the vert grip KWA model (: so happpyyyyy
8:00 Fuck me, where was this video when I was desperately trying to get that pin all the way in? Was pausing and watching others on yt reasamble is so closely but like you said, they don't show you that part..
THANK YOU!!! I have been saying this all along. People keep using the wrong fucking gas in these things. The hop rubbers are shit too. if you use green gas or ANY gas with silicone in it your hop rubber will fail straight away within 20 minutes of play. I fixed one of these for a guy told him what gas to use. Within a week and 20 minutes on the field he was calling me to fix it again. "what gas did you use?" Duh valken green gas- sure Im gonna fix it again and its gonna cost you 30 bucks...Im happy to take your money but if you keep doing what I tell you NOT to do you might as well learn to fix it yourself 'cause Im not gonna do it anymore. as for the recoil spring issue...the force of the bolt gong forward is more than enough to compensate for the lack of spring strength. thats what i found anyhow after playing around with diff springs and short stroking.
@@NegativeAirsoftTech well have to agree to disagree...my customer used silicone green gas in the gun and the hop rubber soaked up the silicone so bad it swelled up and wouldn't hold a bb to save its life. Others have had this experience as well particularly the japanese model. The hop rubber just lose their structural integrity. And the japanese model guns require a completely different hop rubber than the tw version.
@@ghostwalkerairsofttech1947 It was a batch issue, certain oils & so forth used in the creation of certain rubbers are on the no no list of sanctions placed after WW2. The rubber will swell up regardless of what you do, the Japanese rubber is unaffected however the TW versions that KWA & ASG buy up are compiled from lesser quality parts & that includes the hop rubber & the seals in the fill valves - this is why so many KWA mags have issues filling with gas very much like the early WE 1911 mags & often cannot fill past 10 or so shots. Recently this issue has been put to rest by companies such as Army by buying in rubber seals from outside of the sanctioned zones -that's why they have transparent seals in their mags over nitrile seals ;-) The early ASG & KWA manuals would tell you not to lube your hop rubbers where-as they no longer do (again, batch dependant) which is where the rumour that lubing your hop rubber causes breakage comes from. By installing a Guarder rubber into the gun for the cost of about $8 all these issues go away & the gun will hop properly.
@@NegativeAirsoftTech great info Luke...I do lube hop rubbers that is what sent me sailing down this road of using the proper gas in the mp9. And being the japanese model hop rubbers were so hard to come by I didn't want to risk the customers only replacement. The hop rubber for the Japanese model if I recall is larger than the tw model, so a standard size hop rubber will not work in this particular gun. Same for the sealing cup, the tw version is round, whereas the jp version is oblong.
Negative Airsoft boy do I know it lol I tech tm mws rifles for my team and someone in my team got a LM4 that shit was fucked from the factory torn bucking bent tensioner and a scratched to shit inner barrel

What do you actually think about the aap-01 especially internal wise ?

Always nice to start the day to a Negative Airsoft upload. Great vid!
This was super useful and excellent timing! My piston cup just disintegrated and there are so many tips here that I just didn't know about!
this video made me open up my mp9 to see if the bolt was hitting the back properly, good shit mate

Noice.
I really want to run one of these as my primary, are they viable? It'll be used in semi 99% of the time, is the disconnector the main failing part?
Yes, but expect the disconnector to break every several thousand run or so even on semi only.
The disconnector is the first to go normally. I suggest buying the steel upgrade, even if you use mostly semi. Swap out the stock one once it breaks.
@negativeairsoft the music you had playing in this video sounds like it should be played with the astartes animation.
they're nice... but its no Kriss Vector though is it!
Nice video as always. The MP9 is a dream to play with as long as it works. I have heard people claim that loading the thing without locking the bolt back risk breaking to loading arm. Any guess if that may be true?
S4zzie it is true in that you can wear down the bolt catch and eventually when you fire your last shot of a magazine, the bolt won’t lock back
@@ritzcar9011 i don't know how common it is but it had that problem when I bought mine second hand.

My MP9 is disassembled for the moment but I am planning on adding epoxy where the bolt meets the bolt catch so it hopefully does not wear down.
S4zzie I haven’t run into that problem yet, I just lube it before every game depending on how much I shot the last one, I run hpa tapp so
