Product Description The Aero Precision VG6 Gamma 556 is a premium muzzle brake and compensator hybrid engineered to virtually eliminate recoil and muzzle movement during firing. Designed using cutting-edge methods including Computational Fluid Dynamics (CFD) and Computer Aided Engineering (CAE), this device represents the pinnacle of modern muzzle technology for the AR-15 platform. Manufactured from stainless steel with a durable black nitride finish, every unit is 100% CNC machined to ensure optimal performance, consistency, and a precise fit on any 1/2"-28 TPI threaded barrel. Optimized for barrel lengths from 10.5 to 18.5 inches, the Gamma 556 efficiently harnesses muzzle gas to reduce felt recoil and keep your sights on target. An updated chamber design delivers improved gas flow and structural rigidity, making the Gamma 556 one of the most effective muzzle devices available. Whether building a competition rifle or a tactical carbine, the VG6 Gamma 556 keeps the VG6 product family at the cutting edge of muzzle device performance.
