GrovTec GTSW298 Mag Cap Swivel Set 1" Push Button Black Oxide Steel Mossberg 590/835 12 Gauge

The GrovTec GTSW298 Mag Cap Swivel Set is a direct replacement magazine cap purpose-built for Mossberg 590 and 835 12 gauge shotguns. Designed as a sling mounting solution, the kit lets the user set up a hands-free carry platform on these pump-action shotguns without modifying the magazine tube or magazine spring.

Constructed from steel and finished in a durable black oxide coating, the GTSW298 mag cap matches the factory appearance of the host shotgun while resisting corrosion and handling wear. The set ships complete with both the 12 gauge mag cap and a standard 1" GT Push Button Swivel, ready to accept any sling fitted with a matching push button socket.

Installation is straightforward, as the factory magazine cap is unthreaded from the magazine tube and replaced with the GrovTec cap, which threads on in its place and continues to retain the magazine spring under normal operation. The included push button swivel then snaps into the cap to provide a secure, detachable sling attachment point that can be removed without tools whenever the user wants a clean, snag-free setup.
