The Gen 4 Micro Bastard from American Precision Arms offers serious recoil mitigation in a clean, compact package tailored for .30‑caliber barrels using 1/2×28 threading. Machined from stainless steel for durability and corrosion resistance, the brake’s self‑timing design simplifies installation—no crush washers or indexing shims required. The refined Bastard‑style ports and the added tunable top ports of the Gen 4 series provide a flatter shooting experience, reduced vertical climb, and a smoother impulse, making it a strong choice for precision and hunting rifles where every ounce and inch matter.
