Griffin Armament – M4SD II Suppressor

 The Griffin Armament design team enhanced the M4SD II to create a superior 5.56mm quick-detach sound suppressor. Forged from over ten inches of high-quality 17-4 stainless steel, the new M4SD II (Mod 4) features a billet-machined “chassis” that houses the internal components. This chassis design provides superior strength and durability compared to standard tube materials.

Through complex and time-consuming machining, the chassis is shaped into a geometry that optimizes performance. It is surrounded by flutes and supporting structures that increase the surface area by 40%, enabling unparalleled cooling. This large surface area is comparable to that of 7.62mm suppressors, helping to reduce the internal operating temperature for enhanced longevity.

The monolithic structure of the blast chamber and tube maximizes safety and heat transfer, mitigating erosion of the baffle surfaces. Additionally, the included flash suppressor front cap further reduces the flash signature for superior suppression.

The M4SD II utilizes our patented high-efficiency baffle technology, providing high performance with low back-pressure for optimal reliability. It offers a wide range of mounting options, including our proprietary SDQD mounting interface – one of the fastest and most durable systems on the market.

Precision-ground to incredibly tight tolerances, the M4SD mounting system ensures minimal and repeatable point-of-impact shift. Built upon extensive research and development, the M4SD-II represents the pinnacle of suppressor performance, equal to the best products available worldwide.

*Silencer interface was designed to fit the USGI A2 government contract compliant muzzle devices. We cannot guarantee fitment with an A2 style compensator due to the broad tolerance range of both import and domestic devices from various brands. For guaranteed fitment, we recommend the purchase of a Griffin GATE-LOK™ muzzle device.
