The Griffin Armament M4SD muzzle devices interface with GATE-LOK suppressors (M4SDK, M4SD2, 30SD, and 30SDK) as well as the QD Blast Shield.

This revised generation 3 M4SD Flash Suppressor provides M4SD sound suppressor end users a high-performance flash suppressor/compensator alternative to compatible A1/A2 Birdcage flash suppressors. The M4SD flash suppressor provides optimal suppressor fit, enhanced flash signature reduction, and reduces muzzle climb. The focus of the Gen 3 revision was to reduce flash as much as possible. Time intensive R&D resulted in a high performance 3 prong flash hider with incredible resonance reduction. These hide flash extremely well and do not ring or ping when fired.CNC machined and outside diameter ground from heat, corrosion, and wear resistant, precipitation hardened, 17-4 stainless steel for maximum durability.
