The M4SD-II sound suppressor is the result of a ten year study of sound suppressor design and rigorous seven year R&D program pulling from lessons learned in environments from computer design, field testing, to actual combat operations in Afghanistan during Operation Enduring Freedom. The M4SD II was designed to provide the optimal combination of lightweight, peak performance, and durability. Our suppressors are computer designed, critically accessed in FEA, tested, and optimized. The M4SD II is CNC machined, and fully TIG fusion welded for maximum thermal transfer and unparalleled strength and durability. Every component in the M4SD II is manufactured from 316L stainless steel, with heat treated 718 inconel baffles throughout. The suppressor bores are wire EDM cut for maximum accuracy and fully blueprinted tolerances. The mounting system and mounts of the M4SD II sound suppressor are precision ground to ten thousandths of an inch for minimal, repeatable and utterly dependable point of impact shift. Built on a mountain of development, the M4SD-II is the pinnacle of performance- the equal of the best competing products available anywhere in the world.
The M4SD-II is a 5.56/.223 silencer that attaches to any standard A2 flash hider platform. While standard mil-spec will work, it is suggested that you mount these on a Griffin Armament muzzle brake or flash hider for a precision fit. Suppressor mounts sold separately.
