The Uncle Mike’s Mag Cap Swivel Set (brand part no. 18112) is a blued swivel kit built specifically for the Mossberg 590 and 835 shotguns. The set replaces your factory magazine cap with a version that has a swivel base built in, adding a forward sling mount without drilling into the magazine tube or barrel. A 3/4-inch wood-screw swivel base handles the buttstock side, and two quick-detach Super Swivels complete the set so you can attach or remove the sling in seconds. Mossberg 590/835 owners who want a proper two-point sling mount without gunsmithing get everything needed in one kit.
