GrovTec GTSW308 Mag Cap 12 Gauge Mossberg 500 1" Push Button Black Oxide Steel

The GrovTec GTSW308 magazine cap is a direct replacement for the factory thumb bolt on Mossberg 500 shotguns chambered in 12 Gauge. Purpose-built to provide a secure mounting point for 1" push button sling swivels, this mag cap lets you run a standard QD-style swivel for fast sling attachment and removal at the range, in the field, or on duty.

Precision-built from steel and finished in a low-glare black oxide, the GTSW308 is engineered to handle the rough service a pump-action shotgun sees in everyday use. It installs in place of the factory mag cap and threads on the same way, giving you sling-ready functionality without permanent modification to the firearm.

100% made in the USA to GrovTec's quality standards for dependable, long-term service.

Set includes:

• One 12 Gauge Mossberg 500 magazine cap (steel, black oxide)
• One standard 1" loop push button swivel

A simple, purpose-built upgrade that turns any Mossberg 500 into a sling-capable, fast-handling defensive, hunting, or tactical shotgun.
