This kit is not legally considered a firearm because the included frame is not yet machined to be functional. This kit legally ships straight to your front door with no FFL required in all 50 states! All you need to do is do four basic machining operations to complete the frame and build your new 1911:

  • Cut the side rails
  • Cut the barrel seat
  • Drill the hammer pin hole
  • Drill the sear pin hole

Completing these steps takes less than two hours, even for first-time builders, thanks to the convenience and ease of use of our 1911 jigs and gunsmithing parts. Easy-to-follow tutorials will allow you to build your 1911 in less than a day, no background check required!

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.
