The PMACA Light Weight Chassis  is a light weight version of the PMACA Standard Chassis.  It is machined from a single piece of 6061-T6 aluminum billet and then anodized.  We have spent extra time machining away extra weight without compromising the strength and durability of the chassis.  If desired the chassis can be painted with Cerakote in a number of colors.  The Cerakote ceramic coating provides additional protection and offers a selection of colors not available with anodized aluminum.  For custom requests, inform us of color choice in notes section.

The use of the chassis allows you to use AR15 stocks, grips, and a Picatinny rail for accessories such as a front grip, laser or flashlight.

Example Build:

  • Standard Ruger® 10/22® receiver
  • Factory Barrel
  • PMACA Lightweight Chassis
  • Magpul Collapsible Stock
  • Magpul Grip
  • Magpul vertical foregrip

    I like it

    Posted by Travis Thibodeaux on Feb 4th 2022

    This is a nice chassis, the receiver fits snug and it has room for a little bigger than .920 barrel. I make my own carbon fiber sleeved barrels and sometimes I use bigger than .920. Only complaint I have is it didn’t come with a buffer tube nut and it didn’t mention that.

    This chassis option is an extremely lightweight, well machined and attractive choice for your 10/22 build. I have purchased (2) of these now and couldn't be happier! The first chassis I bought was the red anodized version and is currently being used as my 22 Charger pistol as a home defense weapon complete with stabilizing brace, red dot, green laser light, 1600 lumen tactical flashlight and 110 round drum. The second one is the chassis for my ultra-lightweight, blacked out, range rifle. Unfortunately, I can post pics with my review. In closing, I give the PMACA LIGHTWEIGHT CHASSIS an earned 10/10. It's a great option and one you will not regret. Oh... I forgot to mention the shipping! Fantastic superfast, shipping. My chassis was on its way just hours after placing my order. On point shipping, on point customer service, on point products. PMACA Manufacturing... simply ON POINT!

    Overall quality is decent, screw connecting tang for grip is offset far to the left. Receiver fits very loose and my receiver pins have space to rattle a bit due to the gap. Pretty disappointing but I saved up for it and it is what it is for the price.

    Charger 22 build

    This chassis is much nicer that stock. I also added a vertical picatinny adapter to the tube and an SB folding brace. Compact and works like a charm.

    Great product

    Posted by Unknown on May 12th 2021

    Excellent quality, super lightweight. Perfect for the “minimalist” look I wanted. Only reason it’s not 5 stars is because at this time the build isn’t finished and I haven’t actually shot it. With flawless function, this is an easy 5 star review

    Lightweight Chassis

    Posted by Joe on Mar 28th 2021

    Love this chassis! It was super easy to install and the product is exactly as described. Be advised though, before purchasing handgrips, make sure the upper tang on the handgrip will fit. Just due to the nature of the chassis, long, curved tangs will not fit without modification. I had to shave part of one off, although that was due to my lack of research/due diligence and no fault of the product.
