The Knights Armament QDSS NT4 5.56mm NATO QD Rifle Suppressor Black is a proven quick-detach sound suppressor engineered for hard use on 5.56mm platforms. Built from durable Inconel with a matte black finish, it interfaces with the included M4QD flash hider or Triple Tap compensator via a robust gate latch connector, delivering repeatable lockup and reliable performance under sustained fire.

This model is ideal for shooters seeking effective sound and flash reduction while maintaining practical handling characteristics. Its compact overall length and moderate weight make it well suited for range use, training, and general rifle shooting where reduced report and muzzle blast are desired. Backed by Knights Armament’s long-standing reputation for precision machining and thoughtful design, the QDSS NT4 remains a trusted choice in dedicated 5.56mm suppression.
