Forged 80 Lower

Forged 80 Lower

All forged 80% lower receivers we sell are proudly manufactured in the U.S.A. from mil-spec forged 7075-T6 aluminum. Each lower is precisely cut using CNC and then left raw for a custom coating, or coated with a matte black Type III hardcoat anodized finish, also mil-spec. Lastly, each receiver blank is engraved with appropriate "FIRE/SAFE" markings for your safety selector lever install once drilled.

Legal to Build Under Federal Law

The forged 80% lower is a nearly finished AR-15 lower receiver that isn’t legally considered a firearm. It’s just a chunk of aluminum in the eyes of the ATF (who officially recognize these units as "receiver blanks") and federal law. What’s so special about that? A forged blank can be shipped to your door, milled out with basic hand tools using a jig, and made into a fully functioning AR-15 rifle or pistol – all without any FFL transfer fees or red tape! It’s completely legal to complete your own 80% receiver. Read our full guide to 80% lower laws - state and federal - by clicking here.

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.

Forged vs. Billet or Polymer

So, why a forged lower in particular? Simple, it’s the toughest. Forged lowers are pressed from raw 7075-T6 aluminum blocks into a rock-hard construction that’ll take some serious abuse. The forged metal maintains a harder surface than a billet or polymer receiver blank and generally shows a more consistent phosphate or anodized finish than other lowers.

How to Finish Your Forged Receiver

Completing your receiver blank requires little to no knowledge and a few tools. With an 80% finishing jig, most of the calculations and measurements are taken care of. You control the tools, follow the instructions, and the jig does the rest. Total fabrication time for a new builder is approximately 30 minutes to 1 hour.

Tools needed

  • 80% jig
  • Drill press or mini-mill
  • Drill bits (included with jig)
  • End mill bit (included with jig)
