The Magpul MS4 Sling GEN2 in Coyote is a versatile one-two point sling designed for AR-platform rifles and other firearms equipped with quick-disconnect (QD) sockets. Built on proven Magpul durability and materials, the MS4 gives you the flexibility to switch between single-point and dual-point configurations depending on your mission—whether you're running tight in a vehicle, moving through close-quarters terrain, or setting up for deliberate shooting where a two-point rig keeps the rifle stable and ready.
What sets the GEN2 apart is the redesigned low-profile slider mechanism that lets you adjust tension smoothly without bulk or hassle. The 1.25" nylon webbing runs longer than the previous generation, so it fits comfortably whether you're running light or geared up with body armor or heavy clothing. Two precision-cast steel push-button QD swivels anchor to any standard QD socket—on lower receivers, end plates, buttstocks, or aftermarket QD mounts—and a custom steel connection ring enables fast conversion between one-point and two-point modes. Swap configurations in seconds, no tools required.
Made in the USA and 100% Berry Amendment compliant, the MS4 combines Magpul's reputation for no-nonsense functionality with the flexibility serious shooters and tacticians have come to expect. If you want one sling that adapts to how you shoot—urban carbine work, hunting, range drills, or defensive scenarios—the MS4 delivers without compromise.

Frequently Asked Questions
Will the MS4 work with my AR lower receiver and stock?
Yes. The MS4's push-button QD swivels attach to any standard QD socket, including those found on lower receivers, receiver end plates, buttstocks, and low-profile aftermarket QD mounts commonly used on AR-platform rifles.
Can I switch between one-point and two-point mode without removing the sling?
Yes. The custom steel connection ring allows you to convert between one-point and two-point configuration rapidly—no tools or disassembly required. Simply attach or remove one QD swivel end from its socket to change modes.
How is the GEN2 different from the original MS4?
The GEN2 features a new low-profile adjustment slider that minimizes bulk while allowing secure, effortless sling tension adjustment. The webbing length has also been increased for a comfortable fit across a wider range of body types and armor configurations.
What's included, and is this sling compatible with non-QD platforms?
The MS4 GEN2 comes with the sling, two QD swivels, and a steel connection ring. It is designed for firearms and gear equipped with push-button QD sockets and is not compatible with platforms lacking QD attachment points.
