Mesa Tactical's LEO Gen II Telescoping Stock adapter and pistol grip system for the Remington 870 shotgun is made specifically with law enforcement in mind. The LEO Stock adapter system is designed to allow shooters the ability to fit AR-style collapsible stocks and pistol grips onto their shotguns, while allowing use of open or bead sights. The versatile telescoping stock adapter system can be fitted with a standard AR-15 grip and telescoping stock, which enables tactical operators to instantly adjust the length of pull of the telescoping stock in order to accommodate differences in individual body sizes or the use of body armor.
