The Mission First Tactical React^TM Magwell Grip is a vertical grip designed for AR15 platforms. This tactical grip keeps the forward hand clear of the magazine well, preventing injury if an overcharged round causes the magazine to eject. Ideally-placed finger grooves provide a secure hold, allowing the user to apply rearward pressure for more stable shouldering. For added convenience, the Magwell grip features a secure, watertight storage compartment. Great for tactical target shooting, the React^TM Magwell Grip easily attaches to your favorite rifle for better muzzle control and accuracy.
