    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.

    Build quality + customer service top notch

    Posted by Kobe on Dec 23rd 2019

    1 - Every accessory fits great, with no alterations needed. Folding adapter, grip, foregrip, & sights are all snug. The finish itself is unbeatable. Top quality product that will last a long time. Also simple and easy instructions included for beginners to follow.

    2 - Customer service was excellent. Originally put an order in for the black, but changed my mind last minute and ask for a red instead and they sent a red one - no questions asked, no hassle. Definitely will be purchasing more from PMACA!

    It fit perfect and zero play. I assembled It in less 20 minutes. i wish i could give 6 stars. I am still waiting on the 15 inch carbon fiber hand guard and it seems to be on back order.

    Multi chassis for Ruger Charger

    Posted by Fredi on Dec 10th 2019

    Ordered the red anodized chassis for my wife gun. Wife love the red color.Also added a Shockwave 11 KAK buffer tube , brace , slimline flash can, and a Kidd’s 6inch bull barrel. Chassis is solid ,light weight and well made. Now waiting to install an aluminum barrel shroud to complete the build. Customer service is great. All emails answered promptly by Dwayne. Shipping was on time. Will buy again for my second 10/22 build.

    If you have a 10/22, or you're thinking about starting a build. Let me tell you something very important before you start. DO IT! I did a "Charger" pistol build, and it turned out amazing. Perfect construction on the PMACA stuff. Can't fault them on anything. Fit is perfect, color is sweet, finish is cherry. I'm stoked on my build.
