1911 Jig

1911 Jig

You've heard the news: Yes, you can legally build a 1911 from scratch, no FFL required, no background check needed, under federal law. To do that, you need an 80% 1911 frame. Officially designated a "receiver blank" by the ATF, the 80% frame is a nonfunctional 1911 frame that isn't considered a firearm. You, the proud future owner of your custom handgun, will need to perform some basic machining to make the frame functional: Cut the slide rails and barrel seat, and drill two pin holes (here's a guide on how to do it)

State Laws May Vary

Some states have banned 80% frames and certain firearm parts, or have otherwise restricted the sale and ownership of products we sell. So, be sure to check your local and state laws. We can’t ship our products to certain states. Please check our Shipping & Return Policy before placing an order (see restrictions).

Stealth Arms 1911 Jig: No Experience Required

To complete those steps, you need an 80% 1911 jig. The Phantom 1911 Jig by Stealth Arms is designed to work all the 1911 frame blanks we sell, coated or un-coated, including all the combo kits listed on here. Combo kits conveniently include a Government- or Commander-sized frame in 9mm or .45 AACP, drill bits, and the jig. The jig is a hand tool, providing a special bladed "cutting car" that you'll operate to cut the frame by hand. It also comes with pre-drilled pin hole guides, so there's no measuring or complex calculations required.

Finish your frame in 30 minutes to 1 hour. It really is that easy.

Completing the frame, including cutting the slide rails and barrel seat by hand, is surprisingly simple: Each frame is constructed from lightweight yet rugged 7075-T6 forged aluminum. Unlike the 1911's original bulky steel frame (which would be almost impossible to machine by hand) the aluminum 80% frame can be completed in 30 minutes to 1 hour, providing a lighter pistol that feels better, yet is just as rugged and capable. Grab a jig and pair it up with one of the complete 1911 build kits, and you'll have every part and tool you need to build your new handgun with a single order, shipped straight to your front door.
