80 Lower

Ready to build an AR-15 at home? You’ve come to the right place: We carry tons of polymer, billet, and forged 80 lowers at the lowest prices! We have the best deals on the internet, and every lower we sell is proudly made in the USA.

Each 80 lower is backed by a Lifetime Warranty, and each is 100% compatible with regular AR-15 parts. Lowers are available raw, or coated with a Type III Hardcoat anodized finish.

Why use an 80% lower to build your AR?

  • No FFL is required to buy or build!
  • 100% compatible with all AR-15 parts
  • Forged, billet, and polymer available
  • Mil-spec 6061 and 7075 aluminum
  • Takes as little as 15 minutes to complete
  • Limited Lifetime Warranty
  • Made in the USA

No FFL is required

It is 100% legal to build a firearm at home for personal use, without any FFL paperwork (the ATF even says so). Some states require serialization of your lower before completion (like California buyers).

But buying and owning an 80 lower requires no FFL transfer, no paperwork, no extra taxes, no special fees, no waiting period, and no government bureaucracy. Click “Add to Cart”, check out, and your lower’s on its way.

How it works

To finish your lower, you’ll need an 80 lower jig. The jig looks like a small metal box and acts as a miniature “work station”. The jig sets up and orients the lower for you. It also measures everything and it shows you where you need to drill holes and machine raw metal.

Tools needed

That really is all you need! The jig does all the work. It tells you where to drill, how far to drill, and where to cut with the end mill bit. All you need to do is put your hands on some power tools and let the jig do the rest. Total machining time is usually less than 2 hours. Some jigs get the job done in 15 minutes!

Available in most calibers

We have 80 lowers available for the most popular AR calibers! Pick an affordable forged unit for a 5.56 or .223 build. Want to build an AR-10 clone? Grab a .308 lower that’s compatible with DPMS Gen 1 and LR-308 hardware. Want a pistol caliber? We have the new AR9 lower, too.
