Mesa Tactical Beretta 1301 LEO Gen II Tele Hydro Recoil Collapsible Shotgun Stock Kit Standard Damping 12 Gauge Black. 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.
