Griffin Armament
Overview
The Griffin Armament 1/2-28 Taper Mount Hammer Compensator is designed for 5.56 NATO caliber firearms, effectively reducing muzzle rise and improving follow-up shot accuracy by redirecting gas in a manner that counteracts recoil. With its 1/2x28 thread pitch, this compensator easily mounts to standard AR-15 barrels, making it a practical choice for builders looking to enhance their shooting performance. This compensator commonly appears in carbine gas system builds, where the balance of control and accuracy is essential.
