fitting of muzzle brake / compensator to AR-15 or other 5.56 / .223 /
.22 / 9mm rifles, carbines or pistols utilising standard 1/2"x28 or
1/2"x36 thread (it's really only the diameter - 1/2", rather than the
thread pitch that counts with a crush washer).
- The same steel crush washer as included in CMARMB Muzzle Brake kit
- Difficult to find in Canada at reasonable cost - until now!
