About 80 Lower Jig, Co.

The 2nd Amendment is a staple of the American dream. The right to bear arms and to defend one’s family, home, and sovereignty against both foreign and domestic enemies is why America is the last remaining superpower still (mostly) run by the people and our (mostly) elected officials. That freedom is under threat.

That’s why 80 Lower Jig, Co. exists. We’re proudly located in Indianapolis, the home of one of America’s greatest races, the Indy 500. We stick to that love of steel, fire, and forged things by building some of the nation’s highest quality 80% AR-15 and 1911 lowers and jigs.

America’s Best 80% Lowers and 80% Jigs

But what’s an 80 lower and 80 lower jig, you ask? These two items are the answer to the threats being levied against the 2nd Amendment. Completely legal to ship, own, and build in all 50 states, an 80% AR-15 lower is a hunk of aluminum, a piece of metal specifically designed to be easily machined at home with basic hand tools into a fully functional stripped AR-15 lower receiver – just the same as one you’d buy on the shelf (except you get to save a lot of cash by building it yourself).

The same applies to our 1911 frames. They’re not considered firearms until you machine them, and it’s quite easy to do. An 80% jig is a simple piece of equipment that helps you machine your 80% lower at home. This can usually be done in less than two hours.

Everything Ships Straight to Your Door

We exist to ensure your 2nd Amendment right is always preserved by keeping an endless, legal-to-own supply of 80% lowers and jigs, ready to ship at great prices. We afford Americans the opportunity to become proud, home-building gunsmiths of the venerable AR-15 rifle by providing tools, equipment, quality forged and billet 80% lowers, and AR-15 parts.

Everything we sell is made in the U.S.A, and every piece of equipment we sell, including 80% lowers and jigs, is legal to ship to your front door with no paperwork required. All shipments are carefully packaged in nondescript boxes to ensure a safe and anonymous delivery.
