AR-15 MCBS Muzzle Comp Blast Shield System (9mm) (1/2×28 Thread)

(1 customer review)


It’s important to note about this device that the 1/2×28 threads are what attach the 9mm muzzle device to the 9mm barrel (some 9mm barrels, most commonly, will have 1/2×28 and some have 1/2×36 threads – know which thread pitch your barrel has before you order!). This all steel muzzle comp and blast shield system may add a tiny bit of extra weight but everyone around you will thank you! This system will greatly reduce the side blast concussion generated by comp style muzzle devices.
