ABSTRACT:
A sling swivel for removably attaching a sling of flat webbing or other strap material to a rifle or other firearm includes a loop member for receiving the webbing. The loop has a neck extending away from one side. A pivotable shaft carrying a movable link member extends through the neck and is spring-biased to urge the movable link toward the neck. A mounting pin is mounted on one end of the movable link member and is slidably receivable in a hole associated with the neck or a fixed link member. Moving the movable link from its normal position allows the mounting pin to be placed through an eye on a rifle, to attach the swivel to the rifle. The spring-biased pivotable shaft mounting pin is received within the hole. A stop extending from the neck, alongside the movable link, protects the movable link against being pushed away from the neck by an eye of a rifle on which the swivel may be mounted. The loop and neck are preferably of fiber reinforced plastic material, and a fixed link including the hole for the mounting pin is attached to the neck by a rivet whose head protrudes on the side of the neck where the movable link is located. The movable link includes a hole which receives the head of the rivet which connects the fixed link to the opposite side of the neck. The end of the pivotable shaft opposite the movable link may be recessed to help prevent inadvertent release of the swivel from a rifle.
