SureFire rifle muzzle brakes and flash hiders (flash suppressors) are tremendous performance enhancers for your AK-47, AR-15, M4, M14 or other weapon. SureFire muzzle brakes greatly reduce recoil and up-and-right muzzle movement to keep you on target for faster follow-up shots, while their patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. SureFire Flash Hiders provide superior muzzle flash suppression to minimize degradation of your night-adapted vision while helping to conceal your position. Made from heat-treated stainless steel, SureFire rifle muzzle brakes and flash hiders are extremely resistant to gas and particle erosion and will perform perfectly for thousands of rounds. Models are available to fit the existing muzzle threads of many firearm types and calibers.
