Phase 5 FATman Hex Brake, .223/5.56, 1/2×28

The Phase 5 FATman Hex Brake (brand part number FATMAN556) was built to solve the recoil and accuracy tradeoffs competition shooters and precision rifle builders run into with standard muzzle devices. Two large, ventilated baffle chambers create the compensation needed to cut felt recoil, and the first chamber wall sits as close to the barrel crown plane as possible to help preserve the barrel’s full accuracy potential. Two top ports, machined at a 20-degree forward angle, direct spent gas energy in a way that keeps the muzzle flat shot after shot. Machined from black Parkerized steel and threaded 1/2×28, it’s built for .223 Remington and 5.56x45mm NATO AR-platform rifles at 3 inches overall length.
