Blast Forward. The SureFire Warden Direct Thread Blast Regulator for 7.62 mm firearms is engineered to direct the concussive blast of the fired round forward of the system without venting gas to the side, as seen with standard muzzle brakes. This aids in reducing the overpressure felt by others immediately to the left and/or right of the shooter’s firing position. It also limits any dust signature from the firearm when fired from a prone position. The Warden enhances the refined appearance of any firearm with a 5/8-24 threaded barrel, protecting the barrel’s exposed threads from damage or fouling in lieu of a flash hider or muzzle brake.
