Product Details
U.S. made barrel nut (AKA muzzle nut) by AKB. This may or may not be considered a 922r part, but in case it is ever questioned then you are covered.
The size of this part was taken from a Romanian underfolder parts kit and looks very close to a Russian nut off of a milled front end. Threads are 14-1 left hand.
These fit any standard AK with 14-1 left hand threads.
