Product Description

The X4 brake is a muzzle device for large bore applications. The X4 was developed with a large initial chamber that provides a reactive surface for gasses to mitigate recoil. The secondary chamber provides some compensating effect. The X4 was tuned to provide a softer felt impulse over traditional brakes. The X4 is a welcome addition to any large bore rifle.
