American Precision Arms Gen 4 Little Bastard Self-Timing Muzzle Brake (6.5mm, 5/8x24)

American Precision Arms built its reputation on the Little Bastard, and the Gen 4 keeps the self-timing jam-nut that made the line a PRS staple. Instead of a crush washer or shim stack, the brake threads onto the 5/8x24 muzzle and locks level against a jam-nut, so a shooter can index the ports perfectly flat without a gunsmith. The tunable gas-screw system lets you bias the gas ports to counter muzzle rise or lateral drift for your specific rifle and load. On a 6.5 Creedmoor Ruger Precision Rifle, that translates to a flat recoil impulse that keeps the reticle on target through the shot so you can spot your own impacts. The nitrided finish resists the carbon and heat that a heavy PRS round count throws at the muzzle.
