Phase 5 FATman Hex Brake .30 Cal 5/8x24 Black Parkerized Muzzle Brake

The Phase 5 FATman Hex Brake is a heavy-duty .30 Caliber muzzle brake engineered for AR-platform rifles chambered in 7.62x51mm NATO, .308 Winchester, and .300 AAC Blackout. Built from steel and finished in a rugged Mil-Spec Black Parkerized coating, the FATman tames felt recoil and keeps muzzle rise flat so you can stay on target for rapid follow-up shots.

The brake threads on with a 5/8x24 pitch (the standard .30-cal thread pattern) and ships with one crush washer for proper timing against your barrel shoulder. At 3 inches long, 1.26 inches wide, and 5.9 ounces, the FATman adds meaningful mass up front to help settle the rifle between strings, while the hex-shaped exterior profile gives it a distinctive look on the end of the muzzle.

Whether you are running a precision .308 build, a 300 Blackout, or a hard-recoiling 7.62 AR, the FATman delivers the brake performance Phase 5 is known for in a simple, drop-on package.
