In this Brownells Video, Steve and Caleb take the Knights Armament MCQ suppressor out to the Big Springs range for a practical long range test. Designed as a compact, lightweight, low back pressure suppressor, the MCQ is built for shooters who want reduced muzzle blast without the need to adjust their gas system. The team runs the BRN-4 platform from 100 to 500 yards using standard M193 55 grain ammo, comparing performance with and without the suppressor.
This test focuses on real-world usability including sound reduction, recoil impulse, and point of impact shift. The MCQ suppressor is engineered to maintain consistent bolt velocity while minimizing gas blowback, making it an ideal option for AR-style rifles and other gas guns. Watch as they confirm hits on steel targets and evaluate whether this compact suppressor delivers where it counts.
