Phase 5 FATman Hex Muzzle Brake — 5.56, 1/2-28

Description

The Phase 5 FATman Hex Brake is a precision-oriented muzzle device designed for .223 Rem / 5.56x45mm AR-platform rifles. Its two large ventilated baffle sections and chambers provide the compensation needed to reduce perceived recoil while preserving shooting rhythm. The design positions the first chamber wall close to the barrel crown to maintain barrel accuracy. Two top ports are machined at a 20° forward angle to help direct gas and support flat, consecutive shot-to-shot results.
