The Uncle Mike’s 18012 Mag Cap Swivel Set is a purpose-built magazine cap and sling swivel kit for Remington 870 and 870 Youth 12 gauge shotguns. Constructed from durable steel with a blued finish, this quick detach system uses Uncle Mike’s Super Swivels to provide a secure, smooth attachment point for 1 inch slings while replacing the factory magazine cap.

This set is ideal for hunters, range shooters, and anyone who wants to add a dependable sling to their Remington 870 without permanent modification. The included replacement magazine cap with swivel base, 3/4 inch wood screw butt-stock swivel base, and two Super Swivels work together to create a clean, functional carry setup that stays out of the way until you need it. It reflects Uncle Mike’s long-standing reputation for practical, well-engineered firearm accessories.
