The PMACA Standard Chassis is a single piece of 6061-T6 aluminum precision machined from billet, and then anodized.   If desired the chassis can be painted with Cerakote in a number of colors.  The Ceakote ceramic coating provides additional protection as well as a selection of colors not available from anodized aluminum.

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

    10/22 standard chassis

    Posted by Csv on Aug 2nd 2023

    Mounted on Magnum Research 10/22. The original stock was adequate, but fore end was flexy. Changed to this solid aluminum stock, and added AR15 furniture. Super solid, and still very light for fast target acquisition. Everything was super straight forward to put together.

    The PMACA standard chassis is a beautiful match with my 8" threaded bull barrel, bipod, hogue grip and reflex sight.

    Beavertail grips won't fit unless you cut them down only reason I docked a star is because it didn't fit this very well could've been in the description and I just didn't read I'm unsure
