• Griffin Armament’s dedication to the never-ending pursuit of providing maximum value to customers knows no bounds. The development of the newest silencer in the GATE-LOK™ line is no different! The Griffin Armament 30SD-K was born from multi-level customer feedback that reported the desire for a shorter .30 caliber QD silencer.

    Griffin Armament suppressors are on the cutting edge of the industry and trusted for their reliability. Unique to Griffin QD family silencers is the 30SD-K’s GATE-LOK™ mounting interface. The mounting system is one of the fastest on the market and accommodates USGI spec A2 compensators* (in 5.56mm) as well as Griffin’s proprietary performance-rich muzzle device options. The 30SD-K brings advanced CNC manufacturing, wire EDM, TIG fusion, and filler rod welding together in one full-spectrum product.

    Pursuing maximum performance, the design team incorporated Griffin Armament’s patented ECO-FLOW™ Baffle technology into the 30SD-K. The 30SD-K offers an incredible 127dB 300BLK subsonic sound signature, 136dB on 5.56mm, and 138dB on .308. The 30SD-K offers users a wide range of platform coverage from 7.62mm, 300BLK, 6.8spc, and 5.56mm using our variety of 30SD and GATE-LOK™ mounts. 5.56mm firearms are supported with this suppressor via the use of any of our GATE-LOK™ mounts in addition to compatible A2 compensators*. Additionally, the Gate-Lok mounting system does not suffer from the wear-prone issues of ratcheting systems common to the marketplace. This mounting system was designed to provide trouble-free use. 30SD and GATE-LOK™ mounts in the Gate-Lok family are precision ground to ten-thousandths of an inch for minimal, repeatable, and completely dependable point of impact shift. Built on years of development, the 30SD-K is the pinnacle of performance- the equal of the best competing products available anywhere in the world.

    *Silencer interface was designed to fit the USGI A2 government contract compliant muzzle devices. Griffin does not 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 mount.
