The MB556K muzzle brake fits the Colt Commando, M4, M16, HK 416, and other 5.56mm (.223 cal.) semi-auto, bolt-action, or assault rifles with Mil-Spec 1/2-28 muzzle threads.
The MB556K muzzle brake greatly reduces both recoil and up-and-right muzzle movement to keep you on target for faster follow-up shots, while the patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. (To see one in action, click on the video button at left.) Machined from heat-treated stainless steel, finished in a tough, corrosion-resistant coating, all SureFire muzzle brakes are extremely resistant to gas and particle erosion and will perform perfectly for thousands of rounds.
The MB556K muzzle brake also serves as a precision, rock-solid adapter mount that enables rapid no-tools attachment of SureFire FA556K, FA556-212, FA556MG, MINI, or MICRO suppressors to the Colt Commando, M4, M16, HK 416 with 14.5" or longer barrel, and to other 5.56mm (.223 cal.) semi-auto, bolt-action, or assault rifles with Mil-Spec 1/2-28 muzzle threads and (due to slight suppressor overlap) first .170" of barrel behind the threads clear of obstructions and no more than .800" in diameter.
For compatibility of military equipment with this muzzle brake, see chart.
NOTE: SureFire muzzle brakes and flash hiders also serve as adapter mounts for our Fast-Attach® sound suppressors. If you do not plan to attach a SureFire sound suppressor to your firearm, we recommend choosing a shorter-length muzzle brake or flash hider. SureFire muzzle brakes and flash hiders that mate with our overlap suppressor models are longer in order to extend rearward over the barrel, a feature that is unnecessary unless mounting an overlap suppressor.
