This chassis is Made in the USA and is covered by a LIFETIME WARRANTY.

It is made from PA12 Nylon using Selective Laser Sintering. It is compatible with both the Barra 1100z and Beeman Chief II. On both of these airguns the weight is reduced by more than a pound over the OEM stock while also adding an AR pistol grip and adjustable buttstock.

It accepts AR Grips with or without beavertails. The Grip is secured to the Polymer chassis with a steel screw and stainless steel nut inset into the grip rib. I like the Magpul MOE K the most, but folks who like a larger will want to go the the K2 or K2-XL or you can choose “no grip” and use your own.

It accepts AR15 and AR308 extension tubes. We offer both AR308 and AR15 Milspec tubes and a few different buttstock options. I suggest the AR308 and Magpul MOE buttstock. Choose the AR15 tube for most compact if you don’t need the longer LOP of the AR308.

AR15 Tube with Magpul MOE LOP – 10.75 to 14.25 inches
AR308 Tube with Magpul MOE LOP – 11.75 to 15.25 inches

The cheek height allows for use of the iron sights on the Beeman Chief II. If you have a high-mounted optic you may need a cheek riser. I’ve listed all the items you may need to complete your build below:

Magpul MOE Milspec Buttstock
AR15 or AR308 Extension Tube (AR308 Recommended)
Castle Nut (Must have for securing the tube)
Magpul .75 in Cheek Riser (Optional)
