Non-NFA device directs blast concussion away from areas left and right of shooter's firing position Precision-machined of rugged stainless steel, heat treated and coated with a durable Cerakote(TM) finish Direct-thread model for quick and easy attachment to 5/8-24 threaded barrelsBlast Forward. The SureFire Warden Direct Thread Blast Regulator for 7.62 mm weapons is engineered to direct the concussive blast of the fired round forward of the weapon 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 weapon when fired from a prone position. The Warden enhances the refined appearance of any weapon with 5/8-24 threaded barrel, protecting the barrel's exposed threads from damage or fouling in lieu of a flash hider or muzzle brake. . Unlike sound suppressors, Wardens are not NFA devices and are available wherever SureFire products are sold, without any of the restrictions associated with suppressors.
