First-time builder? Read our beginner’s guide to the 80% lower receiver.

Billet, Forged & Polymer Lowers

Billet, forged, and polymer 80% receivers are available to satisfy every build and budget. Buy your receiver raw and apply your own custom finish, or keep things simple band grab one with a mil-spec, Type III Hardcoat anodized finish already applied.

Benefits of Using an 80% Lower

  • No FFL is required to buy or build
  • 100% compatible with all AR-15 parts
  • Takes as little as 15 minutes to complete
  • Made from 6061 or mil-spec 7075 aluminum
  • Limited Lifetime Warranty
  • Proudly made in the USA

Why choose us?

An 80 lower receiver isn’t considered a firearm. That means any machine shop or retailer could sell receiver and frame blanks if they wanted to, but that doesn’t mean they are all created equal.

That’s why it’s so important you buy one from a reputable dealer. All our 80% receiver blanks are made in the U.S.A and backed by a Lifetime Warranty. If you find your receiver is defective, we’ll replace it. You’re building a firearm so we strive to make sure the parts you’re buying are safe and functional.

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, so check your local and state laws, too.

No matter where you live, buying and owning an unfinished 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 receiver blank, you’ll need an 80% lower jig. The jig functions like a miniature work station and requires either a drill press or router. The jig sets up and orients the lower receiver for you. It also measures everything and it shows you where you need to drill holes and machine raw metal.

Tools needed

  • 80 lower jig
  • Handheld drill
  • Handheld router or drill press
  • Drill bits (included with jig)
  • End mill bit (included with jig)

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

Lower receivers are 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 AR-9 model, too!
