The Griffin Armament 30SD Flash Comp is a precision-engineered muzzle device built to mount directly to 7.62mm centerfire rifles threaded 5/8"-24—the industry standard for thirty-caliber platforms. Designed as a quick-detach interface for Griffin's 30SD and M4SD suppressor line, this compensator gives you a rock-solid connection point for serious sound reduction while managing recoil and blast signature on the range or in the field. The Flash Comp executes two jobs at once: it tames muzzle flash while working as the mounting hub for your silencer, so you're not paying for redundant hardware.
Built from 17-4 precipitation-hardened stainless steel and finished in tough black oxide, the 30SD Flash Comp is made to handle repeated attachment cycles and hard use without degradation. The design eliminates wear-prone geometry that trips up lesser muzzle devices, and an integral over-travel stop pin keeps everything indexed correctly—critical when you're threading a suppressor on and off. Griffin includes a shim set for headspace tuning, so you can dial in a perfect fit without guesswork or multiple trips to your gunsmith.
If you're building a 7.62mm precision rifle, short-range hog gun, or suppressed hunting rifle and you already run a Griffin silencer, this flash comp is the purpose-built anchor point. It threads on, the pin seats flush, and your suppressor clicks home every time. For pinning and welding, the pre-fit rear pin is ready to go—just screw and press.
