American Precision Arms Gen 4 Micro Bastard 6.5mm 1/2x28 Muzzle Brake

The Gen 4 Micro Bastard 6.5mm variant from American Precision Arms is a high‑performance, compact muzzle brake engineered for precision rifles using 6.5mm cartridges (.264" bullet diameter or smaller). With its 1/2×28 threading and nitrided steel construction, this brake offers durability and a streamlined profile suitable for sporter or heavy sporter barrels. At approximately 0.850" OD, 2.4" length, and 2.3oz weight, it delivers excellent recoil reduction without undue bulk. The self‐timing nut installation removes the need for shims or crush washers, while the Gen4's tuned “Bastard” ports and calibrated top port system deliver flatter shooting, reduced muzzle rise, and a softer perceived recoil impulse. Ideal for a 6.5mm hunting or target rifle where every inch and ounce counts. American Precision Arms Gen 4 Micro Bastard 1/2x28 6.5mm Nitrided Self Timing Muzzle Brake G4M1265N
