AR15 Lower Assembly

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!

State Laws May Vary

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
