Welcome to ak-builder.com!
These brakes are CNC machined then marked "U.S.A." and count as one part towards your 922r compliance. Black Oxide finish.
I personally machined these brakes to look just like the originals. All of the other slant brakes on the market are missing the cut on the back side of the brake. 1.31" long/0.8 oz.
These fit any standard AK with 14-1 left hand threads. These won't work on a Polish Tantal though.
This item is made in the United States and counts as a 922r compliant part.
