Magpul MAG502-BLK RSA Rail Sling Attachment AR-15/M4/M16 Black Steel

The Magpul MAG502-BLK RSA (Rail Sling Attachment) is a low-profile forward sling attachment point designed for the AR-15/M4/M16 platform. Machined from nitrocarburized steel for outstanding wear and corrosion resistance, the RSA provides a secure anchor for the Magpul MS2 and MS3 slings as well as other clip-in two-point sling systems.

The RSA clamps directly to any 1913 Picatinny rail with no special tools required, giving shooters a clean, snag-free mounting solution that sits close to the handguard. It has been proven to withstand stress tests of over 300 pounds while weighing only 1.3 ounces, making it a lightweight, durable upgrade for any modern sporting rifle running a clip-in sling.

Made in the USA and finished in black, the MAG502-BLK is the go-to forward sling loop for the AR-15/M4/M16 platform. Mounts to any MIL-STD-1913 Picatinny or STANAG 4694 rail.
