SKU: 1911F-45GSAB


Our 5” Government Anodized Black 1911 Frame is one of the most affordable 80% 1911 frames available on the market – and it’s also one of the most well-built. Made from precisely CNC-machined 7075 T6 aluminum and featuring a black anodized finish, this 1911 frame’s made from the same stuff as a military-issue M4. Weighing 60% less than a conventional steel 1911 frame, our 5” Government Frame is more comfortable to carry and shoot.

This 80% 1911 frame is not considered a firearm by any legal definition. Owning it is 100% legal in all 50 states, no paperwork required. You don’t even need to fill out any paperwork to machine the frame into a functional 1911 frame. Machining requires little to no experience thanks to our 1911 jigs and parts. Machining can be done in about 1 to 2 hours:

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

Proudly made in the USA, this 80% 1911 frame costs pennies on the dollar and competes with some of the highest tiers of the legendary 1911 lineup.

1911 80% Frame Features

  • Manufactured to be used with a 5″ barrel
  • Constructed from 7075 heat treated aluminum
  • 60% lighter than steel 1911 Frames
  • NO FFL Required to purchase

Perfect bit

This was just what I needed. It cut smooth and clean and now my lower is ready to be made into a full AR-15.



I was able to complete about 5 lowers unit the end mill gave out on me, really happy with the durability of the end mill bit. I was putting it through hell and it kept eating!
