The Mission First Tactical React^TM Torch and Vertical Grip is a combination of a vertical grip and an illumination mount. This vertical grip/torch mount combo is compatible with lights and lasers with diameters of 0.75 inches, 0.825 inches, and one inch. A thumb switch allows you to activate wired-switch or rear-activated lights, and a lock-out switch prevents unwanted or accidental light activation. The vertical grip features grooved surfaces to provide a secure hold for improved muzzle control and accuracy. The flat, no-slip bottom provides a stable platform during supported shooting, while the watertight storage compartment features a battery sled to prevent rattle. Designed for convenience, the React^TM Torch and Vertical Grip offers an easy way to add both a torch mount and vertical grip to your rifle.
