PTS Griffin Armament M4SD-II Airsoft Mock Suppressor. The real steel M4SD-II sound suppressor is the result of a ten year study of sound suppressor design and a 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. The PTS M4SD-II Airsoft Mock Suppressor is universally compatible with all four of PTS Griffin Armament's replica devices: the Griffin Armament Tactical Compensator, Brake, Flash Suppressor and Flash Comp.
