Mesa Tactical's receiver mounting scheme for the Mossberg 500/590/835 substitutes custom-machined Chicago fasteners for the trigger pin. The sling is free to rotate about the retainer. A rubber gasket keeps the sling loop from marring the receiver finish. This QD 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. They include a US-made Push Button Sling swivel with the mount.
