    The shade of the red anodizing is amazing, and much deeper than I had thought. Installation is extremely easy peasy. Excited to finish the build and put some pictures up

    Exactly what my Charger needed

    Posted by Brad on Jun 17th 2020

    I went with this product because in the Chargers original configuration it is not ideal for me. The option to add the brace was the main factor for my purchase, and the rail at the front was an added bonus. You can spend $50 on the part to enable to use of an AR style buffer tube/brace. But why would you? For only about $65 more you can have an aluminum chassis and a more positive feel for your Charger. My only flaw with it is the paint/anodizing that is applied. It’s that coating that when you’re fingernail grazes it slightly it will leave a mark, but rubs away every time. Time will tell of it holds up, but from my initial impressions it looks like a huge win! I love the flexibility you have with it also. If you’re debating buying it, just do it.

    It took a while to find, this is the chassis for me. The dimensions are right, fit and finish are superior. Thanks for a good all around experience.

    Love the chassis, great fit. Just wish the grip area would blend in better with trigger guard.

    Build quality

    The multi chassis I received was amazing. Really took my 10/22 to the next level with the sleek light weight design and being able to put an AR stock and grip on it feels a lot better in my opinion. Priced about right and I mean you seriously can’t beat this chassis. The others fee like cheap made toys by comparison

    PMACA multi chassis is just what I was looking for. My only complaint would be the coating is thin and a little rough so I ended up painting it. I would recommend this to anyone looking to build a Ruger 10/22.
