    A muzzle brake, compensator and flash supressor hybrid, the VG6 Precision Epsilon 556 is a top performer with a bargain price.

    The Epsilon 556 enjoys much of the same design as VG6's other signature muzzle device, the Gamma 556.

    However, the Epsilon 556 has no ports at the 12-oclock position, allowing an uninhibited view through sights and optics.

    Six valve holes are also ported in to the underside of the Epsilon as well to aid in flash suppression. 

    Similar to the Gamma 556, the product is designed based on research yielded from the math-driven science of computational fluid dynamics.

    As a result, the product instantly improves recoil, muzzle movement, resulting in better aim and feel while shooting
