Frequently Asked Questions

What tools do I need to finish this 80% lower?

You only need a drill press or a sturdy hand drill, a vise, and the tools included in the kit: the 7/16″ end mill, the 5/16″ and 3/8″ drill bits, and the provided Allen wrench. The precision jig guides all your cuts.

Is this lower compatible with all AR-15 uppers?

Yes. The Polymer80 G150 uses standard MILSPEC dimensions and will fit any commercially available AR-15 upper receiver in calibers like 5.56 NATO, .300 Blackout, 9mm (with appropriate mag block), and .22LR.

How durable is a polymer lower receiver?

Polymer80’s proprietary composite and solid-core design provides significant strength. The stress points around the buffer tube and fire control group are reinforced. For standard use and calibers, it offers excellent durability and a major weight savings over aluminum.
