Comstock Muzzle Brake 5/8×24 9mm Compact Facemount – No-Shim Design

The Comstock Compact Facemount Muzzle Brake in 5/8×24 thread pitch is purpose-built for 9mm pistol-caliber carbines and rifles, making it an ideal upgrade for PCC competition builds, home-defense carbines, and custom projects running barrels without a proper shoulder. At just 1.6 inches in overall length and weighing only 1.8 ounces, this compact muzzle brake delivers meaningful recoil mitigation without adding unnecessary bulk to your setup.

What sets the Comstock Facemount apart is its no-shim timing design. Traditional muzzle brakes often require shimming to correctly align ports — a time-consuming process that introduces room for error. The Comstock eliminates that hassle entirely. Thread it on, torque it down with standard 13/16-inch wrench flats, and get back to shooting. The facemount design ensures secure, consistent fitment every time.
