The Magpul RSA® (Rail Sling Attachment) provides a low-profile, forward sling mounting point for rifles equipped with a 1913 Picatinny rail. Designed for use with clip-in sling systems, it is fully compatible with the Magpul MS3 Sling, Magpul MS4 Sling, and other similar clip-style sling attachments.
Constructed from QPQ salt bath nitrided steel, the RSA offers exceptional wear resistance and corrosion protection, ensuring long-lasting durability even in demanding environments. It securely mounts to any standard 1913 Picatinny rail, providing a stable forward attachment point for improved sling positioning and weapon control.
Despite its compact size and lightweight design—weighing just 1.3 ounces—the RSA has been stress-tested to over 300 pounds, delivering outstanding strength and reliability for professional and tactical applications.
