Mesa 90430 Push-button Sling Swivel for Moss 500

The receiver mounting scheme of our sling and hook loops for the Mossberg
500/590/835 substitutes custom-machined Chicago fasteners for the trigger pin.
The sling or hook loop is free to rotate about the retainer. A rubber gasket
keeps the sling loop from marring the receiver finish. Our Push-button Sling
Swivel Mount is secured to the shotgun in the same way as the sling loop, except
it allows the use of a sling swivel that can be removed from the weapon with the
press of a button. We include a US-made Push Button Sling swivel with the mount.
