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.

    Sturdy chassis and all parts fit perfectly. No issues putting together with 10” KIDD bull barrel. Highly recommend for your 10/22 build.

    Standard chassis

    Very easy installation. Used for a Ruger charger build. Fits the receiver perfectly. Added a SB tube and pistol brace. It does require a grip without a beaver tail, all I did was cut off the tail on the grip included with my charger and it fit right up perfectly. Very happy with my purchase.

    Overall, I'm happy with my purchase. I would have rated it 5 stars but there were some annoying tooling marks on one of the bevelled edges. Seems like the cutting tool needed sharpening. Not a big deal but noticeable.

    I wanted a better chassis for my Ruger Charger, and the PMACA Standard Chassis fit the bill. Excellent build quality and a great price to boot!

    I used this chassis for a Steel Challenge build. The fit and finish is outstanding. Magazines lock up tight in this chassis as well. I am extremely happy with the purchase and will use these chassis for all future builds.

    Pistol chassis

    Posted by Jules on Jul 9th 2019

    Received my cercote chassis in record time. Top quality production. Can’t tell you the number of compliments I’ve received at my store and the range. With a 6” barrel and suppressor it is one awesome 22 pistol. Makes a nice rifle also. Will be ordering another soon.

    PMACA Standard Chassis Crimson Red

    Posted by Jerry Corliss on Jun 5th 2019

    I love it. It is perfect for the pistol build I had been planning. The crimson red cerakote is beautiful. The Brownells 10/22 receiver fit with no problem with both the 8.5 inch and 4.5 in barrels. The TAPCO Intrafuse SAW grip was easy to install as well. MAGPUL grips with the beaver tail will not fit without modification (cut off the beaver tail). The chassis came with all necessary allen head screws (grip, and takedown screws). That's a nice touch as many grips do not come with a screw. I am thinking about adding a finger stop to the front rail. Anyway, if you have not ordered one of these in your favorite color, go do it now.
