This tactical grip will slide on and secure to any standard 7/8" rail (picatinny or weaver).  Perfect for adding a forward grip to any barrel shroud or handguard with bottom rail space.  Made form tough, lightweight composite, this grip features two side plates for mounting pressure sensitive switches.  If you are running either a flashlight or laser via a pressure switch, this is the grip for you.  Bottom cap/center tube is removable and provides storage for extra batteries or field tools. 5.5" in length.
