Now you can, and you can do it affordably thanks to our 4.25” Commander Tactical Anodized Black 1911 Build Kit. This kit features a unique, mil-spec 7075 T6 aluminum 1911 frame.

Because the included frame is only 80% machined, nothing in this kit is legally considered a firearm. Your kit ships straight to your front door – no FFL or background check required! Once received, simply machine the last 20% of the frame with one of our 1911 jigs. The process takes less than two hours, even for first-timers, and no experience is required! If you can legally own a gun, you can build this kit at home.

Special Notes:

We can only guarantee that these parts will fit with 1911 frames manufactured by Stealth Arms, due to differences with other manufacturers tolerances. This frame is 80% complete and still needs to be finished by the builder. NO FFL is required for purchase.
