Overview
The EFAB (Enhanced Flash Arresting Brake) combines muzzle control with flash suppression on short barrels. Its patented diverging expansion nozzles diffuse and cool the combustion gas, which Precision Armament says delivers maximum recoil reduction with minimum concussion to the rear and sides of the shooter, and it holds that performance on barrels as short as about 10 inches. That makes it the maker's pick for SBRs, AR pistols, and bullpups, where a reverse-venting brake would be punishing.
The 5.56 model threads 1/2x28 and is 2.50 inches long, 0.900 inch in diameter, and 3.5 ounces, machined from heat-treated 416 stainless with an Ionbond high-temperature CrCN coating. The bottom is closed to keep dust down when prone, and a pilot hole allows permanent pinning to bring a 14.5-inch barrel to legal length. Precision Armament says not to use crush washers with it.
