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

    Ruger charger with shockwave blade.

    Posted by Kaleb on Nov 28th 2017

    Receiver dropped right it. Factory charger pistol grip fit perfect. Put a shockwave blade on it and now it's the perfect silencer host for my element 2. Factory polymer stock weighed in around 10-11 oz. So your only gaining 1 oz and that's nothing.

    Fit my Kidd 10/22 like a glove

    This turned my Kidd 10/22 into my dream rifle. Allowing my to use an xlr stock and whole system serves as a great trainer for my xlr bolt gun.

    Doesn't fit

    Posted by Eric uehana on Jun 7th 2017

    Was excited to put my 22 together, item looked perfect when received. Tried to drop my reciever in and gets halfway then it gets stuck. Tried on the second chassis I ordered and the same problem. Product is milled incorrectly, waiting to see if this company will help me or I gotta help myself
