I have a part that goes over the M1A flash hider ( pre 94 style) It has holes in it. When You put it on , it looks like a muzzle break. What is the name of this part?
It is a compensator, originally developed for the M15 (the heavy barreled variation of the M14) and saw limited use with the M14A1, which was a sort of squad automatic version of the M14 with a pistol grip stock.
