Conceal Your Position. Muzzle Flash is the bane of any infantryman. It provides a clear target indicator for the enemy to identify your position and return fire. SureFire SF3P-50BMG flash hiders are engineered to reduce flash signature by an astounding 99.7 percent, concealing the shooter’s position and increasing warfighter survivability. They also help preserve night-adapted vision and prevent the disruption of Night Vision Devices. The SF3P-50BMG-M2HB utilizes a sleeve and chromoly coupler to attach to the weapon system with no modifications. Constructed of heat-treated stainless steel and chromoly, and precision-machined from USA mill-certified bar stock, these are tools that no Ma Deuce should be without.
