The Knight’s Armament 7.62 QDC CRS-PRG suppressor is a dedicated solution for suppressing large-frame semiautomatic rifles chambered in 7.62mm and 6.5mm calibers. Engineered around KAC’s QDC (Quick Disconnect Coupling) interface, this model attaches securely to all KAC 7.62 QDC muzzle devices. The suppressor is built from 718 Inconel for durability under sustained high-temperature firing conditions and features a 7.9-inch overall length with a compact external profile.

This model incorporates Pressure Reduction Technology (PRT), which minimizes back pressure to maintain near-unsuppressed cyclic rates and reduce gas exposure to the shooter. The PRG baffle geometry is tuned to suppress both sound and flash, with particular emphasis on reducing first-round flash signature. The CRS-PRG is optimized for use on rifles such as the SR-25 and AR-10, especially in precision or high-volume roles where consistent performance and system reliability are critical.No muzzle device, or other accessories are included.
