Not content with excellence, our design team took the 30SD through a series of enhancements to bring you a superlative 7.62mm QD sound suppressor. Forged in the fires of Mount Doom, the new 30SD begins life as over fourteen inches of 17-4 stainless, tool steel, bar stock. We have found 17-4 to provide markedly superior wear resistance, as compared to softer high nickle alloys of good reputation in industry. The heart of the 30SD suppressor is a billet machined "chassis" (tube body), with integrated muzzle device bearing surfaces, which houses the internal components. The "chassis" provides a housing substantially stronger than the strongest tube materials currently available. Through extensive, costly and time intensive machining of the "chassis", a tube structure of superior geometry is derived. The chassis is encompassed by a series of flutes surrounded by supporting structures affording enhanced strength to weight ratio- coupled with a 40% increase of surface area for unparalleled cooling. Reducing the internal operating temperature of the suppressor yields a superior product with a level of durability beyond that of current market options. Monolithic structure of the blast chamber and tube maximizes safety factor and provides maximum theoretical temperature transfer, allowing heat to normalize, mitigating the effects of erosion to baffle surfaces. Integrated at the request of elite tactical units, the included flash suppressor front cap further reduces flash signature in pursuit of suppressed superiority.
Pursuing maximum performance, the design team pursued a baffle revision using our Patent Pending high efficiency baffle technology to create the first truely uncompromised multi-caliber sound suppressor. The 30SD (Mod 2) retained its excellent 7.62mm sound reduction, but dropped ~4DB's in 300BLK, and 5DB's on 5.56mm firearms. The 30SD offers a 5.56mm 132DB sound reduction similar to a market leading caliber specific flagship suppressor, and an incredible 123DB 300BLK subsonic sound signature. The 30SD offers users a wide range of platform coverage from 7.62mm, 300BLK, 6.8spc, and 5.56mm using our variety of 30SD and M4SD mounts. 5.56mm firearms are supported with this suppressor via use of any of our M4SD mounts in addition to compatible A2 compensators.
The 30SD brings advanced CNC manufacturing, wire EDM, TIG fusion and filler rod welding, together in one full spectrum product.
Unique to Griffin QD family suppressors is it's SDQD 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.
Additionally the SD-QD mounting system does not suffer from the wear prone issues of ratcheting systems common to the marketplace.
Our mounting system was designed to provide trouble free use. 30SD and M4SD mounts in the SD-QD 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 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. 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 a Griffin mount.
