The Uncle Mike’s 18102 Mag Cap Swivel Set brings steel construction with a blued finish to your Mossberg 500 shotgun. This quick-detach accessory features a 1″ loop and includes a factory magazine cap with swivel base already installed, plus a 3/4″ wood screw buttstock swivel base and two Super Swivels with Tri-Lock. Installation is straightforward—simply unscrew your existing factory magazine cap and replace it with the new cap, then attach the buttstock swivel base to the stock.
The Super Swivels with Tri-Lock deliver the strength Uncle Mike’s is known for while adding extra security against accidental opening. The Tri-Lock system allows quick detachment like standard QD swivels, but prevents unwanted separation with its additional locking mechanism. Silent operation and a reliable fit make these swivels well-suited for hunting rifles and shotguns, and you can add sling swivels to your Mossberg 500 without modifying the firearm itself.
