Add a sling to your Remington 870 or youth 12-gauge shotgun without drilling, tapping, or permanent modification. The Uncle Mike's 18012 Mag Cap Swivel Set replaces your factory magazine cap with one that has an integrated swivel base already installed—no gunsmithing required. This is the fastest way to rig a carry sling on a pump shotgun that wasn't designed with factory sling studs.
The set includes two Super Swivels with 1" quick-detach loops, so you can swap slings or remove them entirely without tools. The magazine cap swivel uses a steel blued finish that matches traditional shotgun hardware. Installation is straightforward: unscrew the existing magazine cap and thread on the new one. For the buttstock, a 3/4" wood-screw swivel base lets you mount the second Super Swivel to complete your sling setup.
Whether you're rigging a hunting shotgun for hands-free carry in the field or setting up a youth shooter's gun for safer handling at the range, this swap-in solution beats drilling holes. The quick-detach design means you can run the shotgun as a sling gun one day and put it back to stock configuration the next.

Frequently Asked Questions
Will this fit my Remington 870?
Yes, the Uncle Mike's 18012 is designed specifically for the Remington 870 pump shotgun and compatible youth models in 12 gauge. Installation requires only unscrewing the factory magazine cap and threading on the new swivel cap.
Do I need to drill holes in my shotgun to install this?
No. The magazine cap swivel replaces your factory cap directly. The buttstock swivel base uses a 3/4" wood-screw mount for the stock, so you only drill a small pilot hole if needed—no large permanent modifications required.
What does "quick-detach" mean, and can I swap my sling?
The 1" quick-detach loops allow you to connect and disconnect a sling instantly without tools. You can attach a sling when you need it and remove it just as quickly, or swap between different slings.
What's included in the set?
