The Knight’s Armament CRS-3 5.56 NATO QD Rifle Suppressor Black is a compact, high-performance suppressor built around the proven KAC QDC mounting system. Designed for 5.56×45 NATO AR-15 pattern rifles, it delivers excellent sound and flash reduction while maintaining reliable cycling and consistent point of impact. Pressure Reduction Technology (PRT) and a vented chamber design help manage back pressure, keeping gas blowback low and shooter comfort high.

Its full-auto rating and durable construction support extended firing schedules without user maintenance. The CRS-3 reflects Knight’s Armament’s reputation for meticulous engineering and innovative suppressor design.
