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.

    Every 11 yr old boys dream

    Our eldest son wanted his 22 to look like an AR, so we purchased this chases, a flash hider, red dot scope and a few more things and decked his gun out for his birthday. He is ecstatic!

    Great fit on Thompson center tcr22 (10/22 clone). Make sure your buffer tube is mil-spec! Some proprietary buffers are safe threaded. Adds a little weight over plastic stock, but a lot better feel as a result. I actually like the weight and am glad I didn’t get the light. Fit and matte finish are awesome! One recommendation is to install helicoil on takedown bolt if you’re like me and obsessively clean your gun every outing.

    Everything I've ordered from PMACA has seemed to be of above average build quality. I would recommend them and purchase from them in the future. Good stuff.

    Nice chassis but.....

    Posted by Tony on Oct 28th 2020

    Great looking chassis. No tool marks in the aluminum and the anodizing is perfect. Only issue is fit. I dropped a New Charger into it and after tightening the retention screw the bolt binds up. I've tried several times to get it but still no luck. Could be an out of spec receiver though. Still a really nice piece.
