Strike Industries' Oppressor represents the next evolution in concussion reduction devices. It provides a no compromise solution for redirecting the gases produced by aggressive brakes and compensators. The advanced internal geometry actively draws the gases out and thrusts the gases forward through vents to accomplish linear braking in order to retain more braking efficiency. It uses a proprietary quick detach mounting system, which can be rapidly installed before transitioning to prone shooting positions, or for indoor use. The Oppressor is compatible with SI muzzle devices which include: Venom-FH, Checkmate Comp, King Comp, MK-9 Comp, J-Comp Gen2, Sierra Comp, and Triple Crown Comp.This model has a black nitride finish.
