The M4SD-II Flash Comp optimally combines the functions of three traditionally separate classes of devices- Muzzle Brakes, Tactical Compensators, and Flash Suppressors. The M4SD II Flash Comp achieved a perfect 5 out of 5 in National Tactical Officers Association testing to achieve the rare, coveted, NTOA Gold seal of approval granted to devices which achieve perfect evaluations. While retaining low concussion muzzle control, the Flash Comp provides a mounting system for the M4SD-II sound suppressor and is pre drilled, and 2.25” length for 14.5” to 16” permanently attached, Non-SBR, M4 carbine builds.
For optimal flash reduction we recommend 14.5" or longer barreled host weapons. Extreme durability, low concussion flash and recoil reduction are the wave of the future- the Flash Comp provides an elegant solution to a complex problem.
