American Precision Arms Gen 4 Fat Bastard 6.5mm 5/8x24 Self Timing Muzzle Brake - Nitride

The American Precision Arms Gen 4 Fat Bastard is a self-timing muzzle brake designed for 6.5mm caliber rifles. The Fat Bastard carries a low-glare black nitride finish and is built for precision and competition-grade shooting where effective recoil management matters.

Featuring American Precision Arms' self-timing design, the Gen 4 Fat Bastard indexes and locks to the barrel without the need for shims. The 5/8"x24 thread pattern is matched to 6.5mm rifle barrels, and the brake measures 3.30" overall length with a 1.10" diameter at its widest point, providing the mass and port area for competition-grade recoil reduction and faster follow-up shots.

Side gas ports redirect blast and pressure to counteract muzzle climb, and the solid rear shoulder seats against a crush washer or timing tool. The Gen 4 Fat Bastard self-timing brake delivers repeatable recoil mitigation for long-range precision and competition use.
