Quickly reconfigurable between one-point and two-point operation, the Magpul(R) 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 Melonite(R) 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.
