GrovTec GTSW90 Mossberg 500 20 Ga Locking Swivel Set - Black Oxide

The GrovTec GTSW90 is a dedicated magazine cap swivel set built specifically for the Mossberg 500 in 20 gauge. It replaces the factory magazine cap bolt to add a secure mounting point for a standard 1" sling swivel, giving your shotgun functional two-point sling carry without permanent modification to the forearm.

The set includes one pair of GT Locking swivels with 1" loops for use with standard push-button or locking sling hardware, plus a 3/4" wood screw swivel stud for the rear of the receiver. A spanner wrench is included for proper assembly of the magazine cap components.

All components are finished in black oxide for a low-visibility appearance and corrosion resistance in the field. The locking design of the swivels helps prevent accidental release while carrying the shotgun over rough terrain in hunting, security, or defensive use.

Designed and manufactured by GrovTec US Inc., the GTSW90 is a purpose-built accessory for Mossberg 500 20 gauge owners who want to add reliable sling capability to a field, security, or defensive shotgun.
