Description

The PMACA Light Weight Chassis  is a light weight version of the PMACA Standard Chassis.  It is machined from a single piece of 6061-T6 aluminum billet and then anodized.  We have spent extra time machining away extra weight without compromising the strength and durability of the chassis.  If desired the chassis can be painted with Cerakote in a number of colors.  The Cerakote ceramic coating provides additional protection and offers a selection of colors not available with anodized aluminum.  For custom requests, inform us of color choice in notes section.

The use of the chassis allows you to use AR15 stocks, grips, and a Picatinny rail for accessories such as a front grip, laser or flashlight.

Example Build:

  • Standard Ruger® 10/22® receiver
  • Factory Barrel
  • PMACA Lightweight Chassis
  • Magpul Collapsible Stock
  • Magpul Grip
  • Magpul vertical foregrip

    This is a great foundation for a lightweight build. Just wish a castle nut was included

    Stellar Chassis

    Posted by Best purchase in a long time on Jan 19th 2023

    I was a little skeptical at first because I’d never heard of PMACA MFG but when the product arrived it was flawless and packed very carefully! I put together my build and took it to the range that next weekend. My Ruger 10/22 has never shot sweeter! I did upgrade the barrel but the chassis is sleek and light weight, exactly what I was hoping for, and it is rigid and durable too! Highly recommended!!!

    Great fit. Nice and snug. Machining looks great also. Anodized finish is flawless. Only reason for the 4 stars is no option for charger model. With no buttock installed, there is an opening on the rear. Pistol version would be awesome

    Light, rigid, & accurate

    Posted by Ben on Sep 13th 2022

    I used the chassis to build my 22LR pistol. It fits compatible 10-22 receivers; in my case, a Brownell BRN-22 which is not a take down version. I matched it with a Whistling Pig 8” barrel and standard AR15 pistol buffer with a brace. It comes in around 3.5lb, well below the 64oz requirement. I’ve only ran about 100 rounds through it but I can easily clang a 6” plate at 75yds without a problem. The chassis is light, holds rigidity, and Unblemished. It needed a little fitting for the bolt to be inserted…a 5 second job with a dremel and small sander stick. The receiver is a tight fit for the BRN-22 but it holds it tight. The unit comes with an action screw so you wont have to buy your own. You’ll have to supply the screw for the AR15 pistol grip. Overall, I highly recommend.

    I bought this for a steel challenge rifle build. Was here in no time then. Some very minor fitting needed. Looks great and so light. Thanks

    Lightweight chassis

    Worked great with my Faxon22 receiver. Easy, lightweight, looks great. I’ll probably be buying a couple more at this price point just for different colors!
