GrovTec G-COMP Muzzle Brake 9mm 1/2x28 Black – AR-9 & Pistol Caliber Carbines

The GrovTec G-COMP muzzle brake reduces felt recoil and muzzle rise on 9mm pistol-caliber carbines and compatible handguns. Designed with dual expansion chambers and side ports, this compensator redirects gas to keep the muzzle flat during rapid fire, improving follow-up shot speed and accuracy. Ideal for competition shooters and home defense setups running AR-9 platforms or threaded 9mm pistols.

Installation is straightforward on barrels with 1/2x28 threading—common on most 9mm firearms. The single-piece steel construction features a durable black oxide finish that resists corrosion and holds up to high round counts. Requires a crush washer or shim kit for proper timing (not included). Compatible with most 9mm carbines and pistols with standard 1/2x28 threads; verify barrel thread pitch before purchase.
