AR15 Lower Assembly

The classic black rifle is split into two primary parts: The AR15 upper assembly, and the AR15 lower assembly. Our mil-spec AR15 lower assembly options include everything you need to turn a box of parts into a range-ready rifle in a single day.

All our AR15 lower assembly parts are compatible with our available AR-15 uppers and 80% lower receiver units! All our lower assembly parts are mil-spec to guarantee compatibility with other retail AR-15 parts.

Quality triggers at affordable prices

In each lower assembly or parts kit, you’ll find a quality, single-stage trigger. Every trigger is made to break cleanly and reliably, with little take-up, over-travel, or creep.

Builders who want to upgrade their lower assembly or parts kits should take a look at the new RA LE145 drop-in trigger! It’s compatible with all our lower assemblies and parts kits and makes for a major, affordable upgrade for your AR-15 rifle or pistol.

No FFL Required

The only part of the AR15 that’s considered a firearm is the stripped lower receiver. That means everything else you buy – including a lower assembly, lower parts kit, upper, 80% lower, or buffer – is not subject to FFL transfers, paperwork, background checks, or other government red tape.

Everything you purchase on our site ships directly to your front door in a discrete, well-packaged box. You’ll have everything you need to complete your AR15 at home, privately and legally!
