    This is awesome.

    Love love love the chassis. It's everything I wanted and at a great price. Makes my 10/22 really stand out from the rest. There was a small blemish on the side where some of the black finish had come off, but it's not a big deal when the product is as well made and satisfying as this is.

    I would recommend this chassis to anyone who asked me.

    Well machined piece

    Posted by Peter on Feb 2nd 2020

    Well machined piece, but Ruger 10/22 does not fit.
    The trigger assembly housing is longer than product is designed for. I have to use Dremel tool and take about 1/8 of inch to make it fit. Otherwise nice product.

    FDE Standard Chassis

    Posted by Kevin Biafore on Jan 24th 2020

    I bought my first PMACA chassis for my Charger Takedown. Once I got it together, shot it and showed off to everyone who would look, I bought another one for my other Charger. These chassis are top quality and look sweet. I wanted the olive drab ceracote but there was a mix-up from website to warehouse inventory count. I called the 800 number and an actual person answered the phone. I can't remember his name (sorry), but he was very apologetic and said the color I wanted should be available soon. I did not want to wait so this man went out of his way to physically lay hands on a standard chassis, and check what colors he had available. Great customer service! I had a tracking number in less than 10 minutes. They do custom orders as well. I highly recommend PMACA! You will not be disappointed. The cost is very fair. You will not regret buying one.

    The fit and finish of my chassis was excellent. I got the standard chassis for a Charger build and was a little concerned that the nose/fore grip would be too short. But it turned out to be the perfect size for what I wanted. I highly recommend this company and would, and may, but another chassis from them.
