Description
The Phase 5 Weapon Systems littleBOY Hex Brake is a muzzle brake for AR-15 rifles chambered in .223 Remington and 5.56x45mm NATO. It uses a ventilated chamber and baffle section intended to reduce felt recoil, helping the shooter keep the muzzle flat and maintain sight tracking between shots.
The brake is machined from steel with a black parkerized finish and has an overall length of 2.5 inches and a weight of 5.3 ounces. Its 1/2x28 thread pattern fits many standard .223 Remington and 5.56 NATO barrels. The chamber wall sits close to the barrel crown.
The package includes a crush washer for installation.
