Magpul – MS4 Dual QD Sling GEN2, Convertible 1-Point / 2-Point

The Magpul MS4® Dual QD Sling GEN2 is a versatile, duty-ready sling designed for rapid transitions between one-point and two-point configurations. Built to meet the same mission requirements as the MS3, the MS4 replaces Paraclips™ with two heavy-duty push-button QD sling swivels, making it ideal for firearms equipped with QD sling cups on receivers, end plates, buttstocks, and handguards.

At the core of the MS4 GEN2 is a low-profile MS1® quick-adjust slider that minimizes bulk while allowing fast, one-handed sling tension adjustment in two-point mode. Increased webbing length ensures a comfortable fit across a wide range of body types and armor setups, making it equally suited for training, duty use, or preparedness-focused rifle setups.

A precision-cast steel QD D-ring, finished with QPQ salt bath nitride, allows seamless conversion between one-point and two-point operation while providing exceptional resistance to wear and corrosion. Combined with Magpul’s custom 1.25” nylon webbing—treated with Near Infrared (NIR) reduction—the MS4 delivers durability, comfort, and reduced IR signature in professional environments.
