ABSTRACT:
A swivel for attaching a sling to a firearm including a plunger depressible for quick detachment of the swivel from the firearm and a selectively operable retainer movably mounted on the plunger for locking the swivel to the firearm when moved to an operative first position. In the operative first position, the retainer is rotatable on a smaller diameter portion of the plunger without being compelled into axial movement therealong, but can be manipulated into a mated position with a threaded larger-diameter portion of the plunger and then into an opposed position where an enlarged head on the plunger opposes a resiliently expansible tapered sleeve on the retainer. With progressively increasing torque, the retainer is then advanceable to an inoperative second position that permits sufficient depression of the plunger to allow release the swivel from the firearm.
