The American Precision Arms Gen 4 Little Bastard (American Precision Arms part no. G4L5830S) brings the same self-timing, tunable-port muzzle brake design to a .30 caliber bore, threaded 5/8×24 with a 2.70-inch overall length and a 1-inch outside diameter. Like the rest of the Gen 4 line, its calibrated top ports are engineered for maximum adjustment, and American Precision Arms tests port size, location, and gas feed to virtually eliminate vertical muzzle movement under recoil. This version wears a stainless steel finish rather than nitride, giving .30 caliber shooters a corrosion-resistant option that matches a stainless barrel or bolt.
