Griffin Armament M4SD Flash Comp 5.56mm


This is the NEW Generation of FlashComp! Designed off of our Hammer Comp, the new flash comp adds an additional sacrificial baffle, offers better flash signature, and is reduced in weight!


The Griffin Armament M4SD muzzle devices interface with our M4SD series of silencers.


The M4SD 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.


Compatible with the M4SD series SD-QD suppressor interface the Flash Comp provides a sacrificial baffle to increase the service life of your silencer. It is also 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. Includes shim set and over-travel stop washer.


Over-travel stop tab should be positioned at the bottom of the muzzle device (6 Oclock).
