American Precision Arms Gen 4 Micro Bastard 1/2x28 .30 Cal Nitrided Self Timing Muzzle Brake G4M1230N

The Gen 4 Micro Bastard from American Precision Arms is a high‑performance self‑timing muzzle brake built for precision and minimal form‑factor. In stainless steel with 1/2‑28 threading it’s optimized for .22 caliber or small‑conversion rifles, giving you serious recoil mitigation in a compact ~2.4" form (≈2.3oz) that won’t overload sporter‑weight barrels. The refined “Bastard” port geometry and internal manifold reduce recoil while smoothing out the impulse and lowering perceived concussion. What sets the Gen 4 apart is the addition of tunable top ports (U.R.P. system) enabling you to fine‑tune the gas flow and muzzle‑rise behavior, making for flatter, more stable shots. With the self‑timing nut system you skip crush washers or shims and get a clean, repeatable installation on barrels .600"‑.850" in diameter. Ideal for hunters or precision shooters who demand effectiveness and lightweight construction without sacrificing control.
