The American Precision Arms Gen III Little Bastard Muzzle Brake is meant for larger barrels with a diameter of .800 - 1.0 inches.

The APA Gen III Muzzle Brake is well suited for the of-hand, run-and-gun, competitor. This lightweight, tunable, self-timing brake features a new nut design and additional port. This new technology allows the shooter to combat recoil, muzzle rise, and lateral movement.

The new lock-nut design also helps with perfect muzzle placement, no carbon ring, no over-rotation, and a stronger lock-up.
