American Precision Arms Gen 4 Little Bastard Self Timing 5/8"x24 Threads 2.70" OAL 1" Diameter 30 Cal

The American Precision Arms Gen 4 Little Bastard is a self-timing muzzle brake designed for .30 caliber rifles with 5/8x24 threads. It features a self-timing jam-nut design allowing the brake to be indexed perfectly level without shims. This Gen 4 model offers calibrated tunable U.R.P. top ports designed to minimize vertical movement during firing and has a tunable gas-screw system to bias recoil and muzzle rise for specific loads. The brake is nitrided or stainless steel finished for carbon and heat resistance, measures 2.70" overall length with a 1" diameter, and is made for precision shooting with reduced recoil and concussion.
