American Precision Arms Gen 4 Fat Bastard 6mm 5/8x24 Self-Timing Muzzle Brake - Steel

The American Precision Arms Gen 4 Fat Bastard is a self-timing 6mm muzzle brake built for hunting rifles, precision rigs, and tactical platforms chambered in 6mm with 5/8"x24 threads. Precision-machined from steel with a durable steel finish, this brake measures 3.30" overall and 1.10" in diameter, weighing approximately 6.4 oz for solid recoil management without piling on excessive front-end weight.

The Gen 4 platform introduces calibrated U.R.P. tunable top ports designed for maximum adjustment, making this one of the flattest shooting brakes in the APA lineup. The top ports can be tuned to generate virtually zero vertical movement, cutting felt recoil and muzzle rise for faster, more accurate follow-up shots downrange.

Thanks to the integrated self-timing design, installation takes seconds with no crush washers, shims, or special tools required. The brake indexes off the barrel shoulder and locks in place, delivering consistent shot-to-shot alignment and repeatable performance run after run.
