The Phase 5 Weapon Systems FATman Hex Brake is a recoil-reducing muzzle device purpose-built for 7.62x51mm/.308 rifles where precision and shot-to-shot consistency matter. Whether you're running a competition rifle, a precision build, or a hard-use .308, this brake is engineered to manage the signature felt recoil and muzzle rise that comes with full-power rifle cartridges—keeping your sight picture cleaner between shots and reducing shooter fatigue on the range or in the field.
The FATman's design centers on two large ventilated baffle sections that channel propellant gases to reduce recoil impulse. The brake features two top ports angled at 20 degrees forward, directing gas energy in a way that promotes a consistent point-of-impact shot after shot. The first chamber sits as close to the barrel crown as the design allows, preserving the inherent accuracy of your barrel. It's a thoughtful engineering choice that separates competition-grade brakes from generic alternatives.
Built from mil-spec parkerized steel in Phase 5's iconic hexagonal profile, the FATman fits the aesthetic of custom rifle builds without sacrificing function. The 5/8x24 thread pitch is the standard for .308 platforms, and the brake comes with a crush washer for easy installation. If you're setting up a precision rifle and want recoil control without compromise, this is solid hardware.
| Caliber | 7.62x51mm / .308 / .300 Blackout |
| Thread Pitch | 5/8x24 TPI |
| Material | Mil-Spec Parkerized Steel |
| Finish | Black Parkerized |
| Included | Crush washer |
Yes, provided your barrel is threaded 5/8x24 TPI, which is the standard thread pitch for .308 rifles. The FATman is also compatible with .300 Blackout and 7.62x51mm in the same thread spec.
The FATman includes a crush washer for installation. You'll need standard muzzle brake installation tools and knowledge or a gunsmith to safely thread it on.
The FATman is designed with precision and competition shooting in mind. The angled top ports and chambered baffle design work to reduce both recoil and muzzle rise, promoting a flatter sight picture and faster follow-up shots compared to basic designs.
