The Magpul® MS4 QDM Sling is a versatile sling system that allows for quick reconfiguration between one-point and two-point operation. It improves on the tried and tested MS4 Dual QD Sling GEN2 by incorporating factory-installed Magpul QDM quick-disconnect swivels. The Magpul QDM is a heavy-duty option that replaces traditional push-button swivels, offering a low-profile design, single-handed manipulation, and a superior corrosion-resistant Melonite® finish. Its high-strength, freely rotating bale prevents sling webbing rollover.

This sling system is compatible with standard QD sling cup interfaces found on many handguards, lower receivers, receiver end plates, and buttstocks. Furthermore, it retains the low-profile quick-adjust slider system from the MS1® Sling, which allows for easy and secure adjustment. The optimized webbing length ensures comfortable wear with all body types and armor configurations. The sling is made in the U.S.A. and meets Berry Amendment compliance requirements.

The Magpul MS4 QDM Sling is designed for rapid conversion between one and two-point configurations, thanks to its factory-installed Magpul QDMs. These swivels and D-Rings are constructed of Melonite® finished steel for strength and extreme resistance to wear and corrosion. Its slider and tri-glides are made of reinforced polymer, making it both lightweight and rugged. The proprietary weave, 1-1/4” wide nylon webbing is strong, abrasion-resistant, and snag-free. It features a tubular construction for anti-chafing user comfort, while colored webbing has Near Infrared (NIR) treatment to reduce IR signature.

Users can adjust the length of the sling quickly and securely, without tails, loops, or other potential snag hazards. The MS1 Slider provides a precise and rapid length adjustment range of 10 inches. The sling mounting is versatile, as it works with the Magpul ASAP® QD for optimal shoulder transitioning in one-point mode, as well as with other end plates, receivers, and buttstocks that have a QD sling swivel socket. It is front-compatible with the Magpul RSA® QD, M-LOK® QD Sling Mount, MSA® QD, and shotgun Forward Sling Mounts, as well as many other QD sling swivel mounts for use in two-point mode.

Overall, the Magpul MS4 QDM Sling offers a strong, rapid, and versatile sling system that is resilient, comfortable, and easy to use. Its unique features set it apart from competitors, such as its proprietary low-profile Magpul QDM swivel, anti-chafing tubular webbing, and wide range of compatible mounts.
