Filling the same mission requirement as the standard MS3 Sling, the MS4 can quickly switch between one-point and two-point configuration.

The MS4 maintains material construction and specifications identical to that of the standard MS3, but features two heavy-duty push-button QD sling swivels rather than the Magpul Paraclip™ aling with a steel D-Ring to allow one to two-point convertibility. This modification allows compatibility with QD sling cups commonly found on lower receivers, receiver end plates, buttstocks, and many low-profile forward QD Sling mounts, including the Magpul RSA-QD.

The MS4 Dual QD incorporates a new low profile quick-adjust Slider which minimizes bulk and allows for secure, yet effortless, sling adjustment. Webbing length has also been increased for a comfortable fit with all body types and armor configurations. Made in U.S.A. and 100% Berry Amendment compliant.


Heavy-duty push-button QD sling swivels for both one and two-point attachment
Durable, precision-cast steel QD D-Ring allows for quick transition from one to two-point mode and is finished with Melonite for extreme resistance to wear and corrosion
Custom 1.25 inch wide nylon webbing material is strong and wear resistant while remaining anti-chaff for user comfort
Low-profile adjustment Slider for adding or removing sling tension in two-point mode with a single-hand
Colored webbing has Near Infrared (NIR) treatment to reduce IR signature

Sling Mounting

REAR/FRONT – Compatible with buttstocks, end plates, receivers, and hand guards that have a QD socket as well as the Magpul ASAP®-QD, RSA®-QD, MSA™-QD, and shotgun Forward Sling Mounts

Great sling!

I have bought some gear from these folks in the past and I keep coming back because the products are solid, the prices are fair, the shipping is quick, the packaging is sturdy and the customer service is efficient. This sling is perfect for me and I would recommend it to anyone who is looking for a great quality sling for their AR.

Thanks for sharing your feedback, Daniel. We're glad you're satisfied with your purchase. Cheers!

Got my Magpul MS4 and it was easy to adjust and fits and feels great. You won’t be disappointed with this purchase. I have a MOE stock, so I purchased a QD connection for it and boom, we’re good to go.

Thanks for sharing your feedback, Richard. We're glad you're satisfied with your purchase. Cheers!

Love this sling.

Magpie makes very good gear. I have bought a cheaper model of this sling and I am much more satisfied with the Magpul sling than with my cheaper model. I will be buying another Magpul sling to replace my cheap sling.

Thanks for sharing your feedback, James. We're glad you're satisfied with your purchase. Cheers!
