The Knights Armament QDSS NT-4 PRG 5.56mm NATO QD Rifle Suppressor FDE is a modern evolution of the classic NT4, combining proven quick-detach mounting with advanced pressure and flash reduction technology. Built around a sintered Inconel body and finished in flat dark earth, it is engineered to vent gas forward of the shooter while preserving the familiar NT4 profile and interface with KAC M4QD muzzle devices.

This suppressor is tailored for shooters who want meaningful sound reduction with less blowback and a cleaner shooting experience during training, range work, or extended sessions. Its design helps reduce stress on the host rifle’s components and significantly cuts first-round flash, supporting more comfortable and consistent use. Backed by Knights Armament’s reputation for precision manufacturing and innovation in signature reduction devices, the QDSS NT-4 PRG is a refined choice for dedicated enthusiasts.
