This sling is the perfect companion to your FLEx swivel, Aug Razorback or KSG Beast muzzle device. It features 2 QD swivels and can convert between single and two point sling in the matter of seconds.
I have been using MS4 slings for a while now myself. You can see them in my videos. I like them so much I decided to offer them to my customers.
Quality you would expect from Magpul.
