Complete 1911 Build Kits
Our 1911 build kits come with every single little part and spring you will need to build the 1911 from start-to-finish. All of those little parts (and bigger parts) and springs are separated into individually-labeled bags to avoid any confusion. As well as containing all of the parts, a 1911 build kit comes with a 1911 80% frame. The frame itself is only “80 percent complete”, so the builder (you) has to complete the remaining 20% of the frame before any parts can be added or the firearm can be built.

Not a Firearm Under Federal Law
The fact that the 1911 80% frame is only “80 percent complete” is a very intentional one. Since the frame of a 1911 is the only part of the weapon that’s technically and legally considered the firearm under federal law, an unfinished 80% frame is considered simply an unregulated part. Only once you begin cutting and drilling the frame is it considered a firearm. That means you can order a 1911 80% frame online and have it shipped to your door without any FFL transfer or paperwork. Aside from being a convenience, an 80% frame just makes sense for a custom 1911 build kit: It's made from lightweight aluminum, so it's easy to machine with hand tools. The finish frame is lighter and more ergonomic than a factory steel frame, too. If you are willing to put in an afternoon's worth of work, the finish pistol you build from scratch will perform like a high-tier retail 1911.
State Laws May Vary
Some states have banned 80% lowers 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).
How to Complete the Included 80% Frame
Fabricating your new frame into a functional unit is easy and requires only a few basic shop tools that you probably have lying around: You'll need a small vise and a hand drill. To cut and drill the frame without any experience required, you'll want to grab the Stealth Arms 1911 Jig. The jig comes with the required drill bits and cutting equipment for finishing the frame, no measuring or special tools requires.
