The Allen Swivel Set for Pump and Semi-Auto Shotguns provides a secure sling attachment solution for firearms without pre-installed hardware. Designed to fit most pump-action and semi-automatic shotguns, this set includes two magnum swivels that accommodate slings up to 1 inch wide. A threaded stud is included for installation into wood or synthetic stocks, while a rotating stud—requiring drilling into the factory magazine tube cap—secures the front swivel. Built for durability and ease of use, this set ensures your shotgun is sling-ready for the field.
