Magpul QD sling loop (MAG540)

The Magpul QD Sling Swivel attaches and detaches a sling with a simple push of a button. It fits standard QD sockets, including those on Magpul UCS, DT, MOE SL and UBR GEN2 stocks and many hand guards and rail mounts.

It installs on slings up to 1-1/4" wide and works with most Magpul slings and adapters. The steel is manganese-phosphate finished for hard use.
