Introducing the littleBOY Hex Brake. A younger, lighter version of the original FATman Hex Brake, which was also created to solve issues faced by many competition shooters and precision rifle builders.

Including 1 large (FAT) ventilated baffle section and chamber to create the compensation needed to reduce the overall recoil felt by the shooter.


The design of the littleBOY Hex Brake allows the chamber wall to sit as close to the barrel crown plane as possible. This design element was included to maintain the full accuracy of the barrel. The iconic Phase 5 Hex design gives the littleBOY Hex Brake the perfect styling that custom gun builders are looking for.
