    Art work

    I installed my long nose chassis on my BRN-22 railed receiver built as a Charger with a KAK brace and it fits like a glove. Fit and finish was top notch and assembly went off without a hitch. Love it! Once I get a pic or two I will try to add them.

    Awesome Product - Awesome Customer Service!

    Posted by Alan on May 15th 2018

    These folks, and their products are fantastic. Immediate reply to inquiries makes this one of the best companies I've dealt with in the 10/22 customization industry. Shipments are fast, products are fantastic and the final products I've put together turn heads at the range. I'm now 7 builds in with more on the way once my custom barrels arrive. It would be hard to switch away from PMACA and I probably won't!

    I am completely impressed by the Chassis and even more impressed by the customer service. The craftsmanship of the chassis is excellent, I am completely happy with everything about it. I ordered the chassis and it wasn't going to be shipped in time for an upcoming match so they sent me an anodized one to use until mine was back from Cerakote. I ordered the long nose chassis and the fit and appearance are excellent. I recommend PMACA to anyone looking for a great chassis. It is so rare to find this kind of customer service in todays world. I will be a life long customer. Thanks PMACA, you guys are AWESOME!!!

    Very light weight

    Posted by Steve on Mar 28th 2017

    Overall this chassis is great. It is very lightweight. But I do not like the gap between the trigger guard and pistol grip.

    Not perfect but very good

    Posted by P. Beaubien on Nov 14th 2016

    Pros: -Lightweight -Compatible with Kidd rear tang -Allows use of standard AR-15 stock and pistol grip Cons: -Design does not require endplate, therefore loss of sling attachment point. -Unable to mount a handguard -Would be difficult to attach a sling with lack of sling swivels

    Long Nose Chassis

    Posted by Dan on May 24th 2016

    I've gone through several 10/22 stocks over the past year - from the standard wood stock, to Nordic Components, to the CBRPS bullpup kit, to a RB Precision build, and the ultimately the PMACA long nose chassis. The latter is by far my favorite. The fit and finish are excellent - I have the armor black model and it's impeccable. Moreover the additional benefits of the extended forearm are twofold: 1) You have more real estate for accessories, and hand placement which helps enhance comfort. 2) You can avoid the Pinocchio look that the short nose chassis systems often result in (especially if you're running a 16+ inch barrel). Despite the extended forearm, the chassis is still incredibly light rivaling any product in the same realm of tactical 10/22 stock offerings; With my Kidd Ultralight 16.5" bull barrel it's almost scary. The grip tang accepts Magpul, TangoDown, BCM, or whatever else you can find with ease (these are the few that I have tried) - which is not necessarily the case with all stocks that feature AR15 pistol grip trunions. I only wish the placement of the tang would allow you a little more space between it and the trigger guard so you could use an unmodified rubber gap filler - but that's such a small detail it's hardly worth mentioning. I also wouldn't mind seeing some mounting points on the sides of the forearm for accessory rails - but again, I'm splitting hairs. If you're on the fence, buy it. PMACA ships quickly too, so you really have no excuse.
