Caliber 5.56 mm (.223 caliber)
Length 4.19 inches


The MB556SSN-1/2-28 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, and allows attachment of the 7.62 mm/.308 caliber SureFire FA762SS sound suppressor to these smaller-caliber firearms.

The MB556SSN-1/2-28 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.

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.
