Quick Disconnect Sling Swivel Technical Bulletin
    It has come to our attention that some of the quick disconnect sling swivels (QD’s) supplied with Colt rifles may not hold proper tension when installed in the butt stock or upper receiver quick detach mounts. As a result, the swivel may detach when moderate pull tension is applied to it. If you are experiencing this problem with the quick disconnect swing swivel on your Colt rifle, please contact Colt’s Customer Solution Center at 1-800-962-2658 (COLT).
