The Rifle Shotgun Sling Swivel Hardware Kit comes with two 1-inch lockable sling swivels that can be quickly detached. These swivels attach to the typical sling swivel stud or holes found on most hunting rifles and shotguns with wood or synthetic stocks. The sling hardware is made of steel and finished in black for durability and looks. The swivels measure 1.25 inches long, with an outside width of 1.6 inches and an internal sling loop width of 1.3 inches. To detach, unscrew the knurled thumb nut, then push in and rotate the side arm 90 degrees to open the mount. Insert the bar into the sling stud, swivel the side arm back over the bar, and tighten the thumb nut to secure the mount. These sling swivels are crucial accessories, enabling the secure attachment of sling strap to rifles and shotguns, thus enhancing carry convenience and firearm maneuverability in the field.
