The Griffin Armament M4SD series of silencers are known for their perfect combination of lightweight and durability whilst still providing peak performances. Their products are a result of a ten year study of sound suppressor design and a rigorous seven year R&D program put together from computer design, field testing and actual combat operations in Afghanistan during Operation Enduring Freedom.
One of the top performing suppressors on the market, the PTS Griffin Armament M4SD-II is back with a second generation that encompasses the latest Griffin Armament suppressor design. The special machined fluted surface design reduces weight while increasing body strength. On the real suppressor, the increased surface area aids heat dissipation for greater longevity and durability during sustained use. The M4SD-II's compact 6.6 inch length aids in maneuverability and minimally affects the weight balance of the gun. It also features Griffin Armament’s trademark SDQD mounting interface, well-known as one of the fastest and most secure mounting interfaces on the suppressor market.
