Surefire Warden Blast Regulator, Multi Caliber, 5.56MM, 7.62MM, Black WARDEN-BK The SureFire Warden Blast Regulator directs 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 Blast Regulator attaches to any SureFire SOCOM 5.56 or 7.62 muzzle device through the same patented SureFire Fast- Attach(R) system found on SureFire SOCOM Series suppressors. Unlike sound suppressors" this product is not an NFA device and is available wherever SureFire products are sold" without any of the restrictions associated with suppressors.
