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

    Sub 4 pound steel challenge rifle

    Posted by Bryan on Sep 10th 2020

    When looking to put a lightweight 10/22 together for steel challenge, I knew I wouldn’t have any issues using the PMACA chassis to hold everything together. Using their lightweight chassis and other various components, I was able to get the rifle to only 3 pounds 12 ounces! Not shabby!

    Almost perfect

    Wish I could give it 4.5 stars.
    Small gripes, but I wish the receiver would work with beaver tail grips, and I wish the grip mount would flow/ sit flush with the trigger guard like the factory 10/22 charger grip mount does.

    Very pleased with your product! The fit and finish is great. With the installation of the arm brace I am having a blast shooting my charger..

    Lightweight, little ugly but serves all the purposes I needed it to!

    I really like the lightweight chassis but it arrived with a small scratch on the top. I do like it and will order another soon. Hopefully the next one will arrive without scratched. If it would have not been damaged I would have given 5 stars.
