Beeman Sling Swivel
This swivel comes in two configurations. A full set (#7410) which consists of two sling swivels and two wood screws and a 1/2 set (#7411) which consists of one swivel and one wood screw.
Unlike most quick detachable swivels, these do not need a socket set into the stock. These swivels install without dismantling your gun. They also feature a white line base spacer for added good looks. And the 1/2" wood screw fits forearms as thin as 5/8".
