Quickly reconfigurable between one-point and two-point operation, the Magpul® MS4 QDM Sling enhances the proven MS4 Dual QD Sling GEN2 by including factory-installed Magpul QDM quick-disconnect swivels. As a heavy-duty replacement for the typical push-button swivel, the Magpul QDM offers an innovative low-profile design, single-handed manipulation, a superior corrosion-resistant QPQ salt bath nitride finish, and a high-strength, freely rotating bale that canalizes sling webbing to prevent rollover. This sling system not only provides the strength, speed and security of Magpul QDM hardware, but also maintains compatibility with the standard QD sling cup interface found on many handguards, lower receivers, receiver end plates and buttstocks. Based on the streamlined two-point MS1® Sling adjustment system, the Magpul MS4 QDM Sling retains the low-profile quick-adjust slider which minimizes bulk and allows for secure, yet effortless adjustment. Webbing length is optimized for a comfortable fit with all body types and body armor configurations. The Magpul MS4 QDM Sling is made in the USA and is fully Berry Amendment compliant.
