XM177 CAR-15 Style AR Pistol Brace - Carbine and Rifle Buffer Tube

Update: Added a version that will work with a rifle buffer tube for a buddy who was having a hard time getting his 9mm to run with any buffer except the rifle buffer setup. Fastens the same except there is now an insert to prevent marring the buffer tube, and the rear bolt that rifle stocks use.

This is a pistol brace styled after the XM177/CAR-15 stock. This is a fixed brace. You will use a 1/4" allen head bolt and nut. The nut slides down inside the brace before sliding onto buffer tube and the bolt will act as a set screw against the buffer tube. The allen bolt head will recess into the brace, or if you prefer the more original look you can use the "adjuster" piece and a longer allen bolt.

This has not been approved by the ATF - use at your own discretion.
