The Magpul MS1 QDM Sling further enhances one of the most versatile line of rifle slings by including factory-installed Magpul QDM quick disconnect swivels. As a heavy-duty replacement for the typical pushbutton swivel, the Magpul QDM offers an innovative low-profile design, singlehanded manipulation, corrosion-resistant Melonite finish, and a high-strength, freely rotating bale that canalizes sling webbing to prevent rollover.
