Description
The Magpul QDM (MAG543) is a heavy-duty quick-disconnect sling mount that replaces standard push-button QD swivels. It fits all standard QD cups and sockets, including Magpul Type 1 and Type 2 socket kits, and uses dual side-release tabs that must be squeezed together, so it can be worked one-handed but resists accidental disconnection. The high-strength bale rotates freely, channels sling webbing up to 1-1/4in and stops it rolling over. Made in the USA from Melonite (QPQ salt-bath nitride) steel, it weighs only 0.7 oz (about 20 g).
