More Compact & Lightweight Muzzle Brake For .223/5.56 Rifles
The Phase 5 Weapon Systems littleBOY Hex Brake 5.56 is the younger and compact version of the original FATman Hex Brake. While the FATman has two large ventilated ports, this littleBOY only has one port to create the compensation needed to reduce the overall recoil felt by the shooter.
This design solves the common issues faced by many competition shooters and precision rifle builders which efficiently controls upward muzzle rise and helps direct the energy of the spent gas to maintain a flat consecutive result shot after shot.
Aggressive One-Piece Design with Parkerized Finish
Phase 5 Weapon Systems littleBOY Hex Brake 5.56 is machined from durable stainless steel and then coated with a Parkerized finish giving ultimate resistance from wear and corrosion. Its design element allows the first chamber wall to sit as close to the barrel crown plane as possible to maintain the full accuracy of the barrel.
This muzzle brake is the perfect upgrade for a compact AR-15 rifle that combines both style and function to achieve the most on your AR-15 build.
