The American Precision Arms Gen 2 Micro Bastard is a self-timing muzzle brake built for .30 caliber AR-platform and hunting rifles (APA part no. G2M1230S). It is precision machined from high-grade stainless steel and threaded 1/2-28. The Gen 2 Series uses a separate timing nut rather than a crush washer or peel washer, so installation takes about 30 seconds at home instead of a trip to a gunsmith. The Micro was designed around sportier-weight barrels, but it has become popular in the AR and 3-gun world for being both lighter and more effective than most brakes in that class. It measures 1.86 inches overall with a .750-inch diameter.
