The Knights Armament 5.56 MCQ-1 Quick Detach Rifle Suppressor FDE delivers compact sound and flash reduction in a rugged, ultra-short package. Built around Knight’s Pressure Reduction Technology (PRT) and a 3D-printed Inconel core, it is optimized for 5.56 NATO rifles where keeping overall length and weight to a minimum matters.

This model adds only about 3.85 inches to the bare muzzle while maintaining reliable cycling and noticeably reduced gas blowback. Its Flat Dark Earth finish blends with modern carbines, and the dedicated QDC interface locks onto compatible KAC 5.56 QDC muzzle devices for repeatable point of impact. Ideal for range use, training, and general-purpose rifle setups where a compact, durable suppressor is preferred, it reflects Knights Armament’s focus on refined engineering and long-term durability.
