MS4® QDM ONE/TWO-POINT RIFLE SLING Reviews & Ratings

MAGPUL MS4® QDM ONE/TWO-POINT RIFLE SLING

Quickly reconfigurable between one-point and two-point operation, the Magpul® MS4 QDM Sling enhances the proven MS4 Dual QD Sling GEN2 by including factory-installed Magpul QDM quick-disconnect swivels. As a heavy-duty replacement for the typical push-button swivel, the Magpul QDM offers an innovative low-profile design, single-handed manipulation, a superior corrosion-resistant QPQ salt bath nitride finish, and a high-strength, freely rotating bale that canalizes sling webbing to prevent rollover. This sling system not only provides the strength, speed and security of Magpul QDM hardware, but also maintains compatibility with the standard QD sling cup interface found on many handguards, lower receivers, receiver end plates and buttstocks.

Based on the streamlined two-point MS1® Sling adjustment system, the Magpul MS4 QDM Sling retains the low-profile quick-adjust slider which minimizes bulk and allows for secure, yet effortless adjustment. Webbing length is optimized for a comfortable fit with all body types and body armor configurations.

The Magpul MS4 QDM Sling is made in the USA and is fully Berry Amendment compliant.

Works like a charm

I picked this up because I wanted a QD sling. I like what Magpul has done with this upgraded qdm system. I don't expect to have any issues with this.

UBR GEN 2 & MS4 QDM Compatibility

First Id like to say this is a nice sling and worth the money. However, on my UBR gen 2 it is somewhat difficult to use the single point sling option. The QDM sling swivels must be squeezed to be inserted. There is barely enough room to do so on the UBR gen 2. Maybe the sling guys didnt talk to the stock guys that day? That being said I really like the sling, I run both a single point and a dual point - depending on situation. I just want to make potential buyer aware that the QDM attachments may or may not be compatible (or somewhat difficult) with their set up.

Great new product

Sling arrived today, was kind of leery ordering but this thing is a great piece of equipment. Adjustments are a no-brainer and it,s obviously built to last. Only drawback is my arthritic/no grip hands as the QD,s have to be squeezed instead of push buttons but they sure wont pop out accidentally. All of you guys and gals with healthy hands will love this rig for switching between 1 or 2 point hook ups. Have had many variations in my time but when I need another sling it will for sure be a Magpul.

Good Sling

Great sling. Very easy to adjust on the go. Going from 2 point to 1 point is easy but not as easy as the standard QD's. It does not get tangled however the QD does have an issue. The roll pins holding the QD bearing in sometimes roll slightly out and interfere with the button, not letting the QD lock in place. Roll pins pushed back in and all is good again. May cause your weapon to fall to the ground when walking slung (which happed to me). I like the sling thou and will continue using.
