American Precision Arms Gen 4 Little Bastard Muzzle Brake, 6.5mm, Nitride

The American Precision Arms Gen 4 Little Bastard (American Precision Arms part no. G4L5865N) is a self-timing muzzle brake built for 6.5mm-bore rifles, threaded 5/8×24 with a 2.70-inch overall length and a 1-inch outside diameter. Its calibrated, tunable top ports are engineered for maximum adjustment, letting the Gen 4 line achieve some of the flattest-shooting performance available in a brake this size. American Precision Arms tests port size, location, and gas feed to eliminate vertical muzzle movement, so recoil is managed mostly in the horizontal plane rather than kicking the muzzle up between shots. The nitride finish adds corrosion resistance for a brake meant for serious round counts.
