Description
Slings tend to be an afterthought until you spend a long day with a rifle hanging off your shoulder, and that's exactly where the Magpul MS4 QDM earns its keep. It's a convertible design that runs as either a one-point or a two-point setup, and swapping between the two takes seconds instead of a trip back to the bench. The 48 to 60 inch length range covers just about every body type and layers over plate carriers or a heavy jacket without a fight.
What Sets the MS4 QDM Apart
The headline here is the hardware. Magpul builds this one around factory-installed QDM quick-disconnect swivels, a heavy-duty step up from the usual push-button swivel. The QDM uses a low-profile shape, a Melonite-finished steel build for corrosion resistance, and a freely rotating bale that guides the webbing so it won't roll over on you mid-transition. Those swivels drop into any standard QD sling cup, so you can run it off handguards, lower receivers, end plates, and buttstocks without hunting for adapters.
Dialing In the MS4 QDM on the Fly
Underneath the fancy hardware, this is still the proven MS1 adjustment system people already trust. The low-profile quick-adjust slider gives you fast, one-handed length changes, so you can cinch the rifle tight against your body for a scramble up a hillside, then loosen it for a quick shoulder transition. There are no tails or loops flapping around to snag on gear. The 1-1/4 inch nylon webbing uses a proprietary tubular weave that's abrasion-resistant and easier on your neck over a long day, and the colored webbing gets a Near Infrared treatment to keep its signature down.
Made in the USA and Berry Amendment compliant, the MS4 QDM is a do-it-all sling for AR-platform rifles and similar systems. If you want one sling that adapts to how you're carrying that day, this is a strong pick.

Frequently Asked Questions
Can the MS4 QDM run as both a one-point and a two-point sling?
Yes, that convertibility is the whole point of the MS4 QDM. You can run it as a stable two-point for carry and support, or reconfigure to a single-point for quick, unrestricted movement. The switch is fast and done by hand with no tools.
What kind of mounts does the MS4 QDM Sling work with?
The factory-installed QDM swivels drop into any standard QD sling cup interface. That means it works with the QD sockets found on most handguards, lower receivers, receiver end plates, and buttstocks. It also pairs well with an ambidextrous QD attachment point for one-point mode shoulder transitions.
How is the QDM hardware different from a normal QD swivel?
The QDM is a heavier-duty replacement for the usual push-button swivel. It has a low-profile shape, a corrosion-resistant Melonite finish on steel, and a freely rotating bale that channels the webbing to keep it from rolling over. It's built to take hard, repeated use while staying quick and secure.
Will the MS4 QDM fit over body armor or heavier clothing?
It should. The 48 to 60 inch adjustable length is designed to fit a wide range of body types and layering, including plate carriers and armor setups. The one-handed slider lets you quickly loosen or tighten to match whatever you've got on.
