The Magpul MSA - (MOE Sling Attachment) attaches directly to the MOE Hand Guard.
The Magpul MSA provides a forward sling attachment point for the Magpul MS3 and MS3 Single QD slings as well as other clip-in sling systems. The Magpul MSA offers a large enough loop for easily attaching a Magpul Paraclip without having to have pin point accuracy in the heat of battle. The Magpul Paraclip can also lock making the Magpul MSA a very secure means to attach a sling to the Magpul MOE hand guard on your weapon. Like the RSA, the MSA is made of steel and is nitrocarbonized for wear and corrosion resistance. Made in U.S.A.
