You'll experience increased stability and control of your firearm with this Heavy Duty Basic Grip from Sun Optics USA. It mounts on a Picatinny rail on the underside of your rifle or shotgun's forend and offers a comfortable means of support and muzzle control. A solid locking recoil pin helps keep the grip locked in place after many rounds. Remove either of the side plates to reveal a space for a remote pressure switch for a light or aiming laser. An internal storage compartment is accessed by a screw cap on the bottom of the grip.
