GRIFFIN SD-STYLE MUZZLE DEVICES

The Griffin Armament M4SD 5.56 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).

The Griffin Armament .30 Caliber muzzle devices interface with our 30SD series of silencers, as well as the QD Blast Shield.

30SD muzzle devices provide high performance mounting option for Griffin QD Silencers as well as a 30 caliber interface for the QD Blast Shield. The Flash Comp , Flash Suppressor, and Muzzle Brake were made with the same performance features as their 5.56mm counterparts but with a 5/8×24 threaded interface and integral overtravel stops. An additional pin is pre-fit for pin and weld applications. The gunsmith only needs to screw the muzzle device on and press the rear pin flush for pinning and welding. The 30SD Muzzle Brake is included with the 30SD silencer. CNC Machined and outside diameter ground from high strength, corrosion and wear resistant, 17-4 precipitation hardened stainless steel, the 30SD muzzle brake is black oxide finished. 5/8×24 threads offer compatibility with most 7.62mm firearms on the market.
