American Precision Arms Gen 4 Little Bastard 6mm 5/8x24 2.70" Stainless Self-Timing Muzzle Brake

The American Precision Arms Gen 4 Little Bastard is a compact self-timing muzzle brake purpose-built for 6mm rifles. Machined from stainless steel and finished in a clean stainless finish, it measures just 2.70" overall with a 1" diameter and weighs only 4.4 oz, keeping added mass to a minimum while delivering the recoil reduction and flat-shooting performance the Little Bastard line is known for.

Cut for barrels with 5/8"x24 threads, the Gen 4 Little Bastard uses APA's self-timing design so the brake orients itself to the bore without fixture timing. The tunable gas system works alongside the trademark APA port design to deliver a trackable sight picture when the rifle is fired, and the updated Gen 4 geometry is engineered to be flatter shooting, softer recoiling, more tunable, and easier to use than ever.

Designed for 6mm rifles with 5/8x24 threaded barrels, the Gen 4 Little Bastard installs as a straightforward upgrade for shooters who want proven recoil control in a compact, self-timing package.
