American Precision Arms Gen 4 Little Bastard 30 Cal 5/8x24 Self-Timing Muzzle Brake - Stainless

The American Precision Arms Gen 4 Little Bastard is a compact .30 caliber self-timing muzzle brake built for rifle platforms. Machined from stainless steel and finished to resist corrosion, the Gen 4 Little Bastard uses a 5/8"x24 thread pattern and measures 2.70" overall with a 1" diameter — a slim, lightweight profile that keeps the brake from intruding on rifle handling or handguard clearance.

The Little Bastard carries American Precision Arms' signature self-timing design: it cuts its own shim during installation, eliminating the crush washer and the guesswork that comes with traditional muzzle brake timing. The new Gen 4 version adds calibrated U.R.P. tunable top ports engineered for maximum adjustment, letting the shooter dial in recoil reduction and muzzle rise to match their preferred feel. It's a straightforward, no-fuss upgrade for any .30 caliber rifle platform.
