The Magpul RSA Rail Mount Sling Adapter Loop is a tough, low-profile forward sling attachment point built for AR-15 platforms running Picatinny rail systems. Whether you're running a Magpul MS2, MS3, or other clip-in sling systems, the RSA gives you a secure, streamlined anchor point that doesn't clutter your rail real estate. It's the kind of simple, well-engineered piece that makes your rifle feel less janky and more purpose-built.
Made from nitrocarburized steel, the RSA resists wear and corrosion without any fuss. It's light—just 1.3 ounces—and mounts to any MIL-STD-1913 Picatinny rail with rock-solid reliability. Magpul stress-tested these to withstand over 300 pounds of pull, so you're not babying this thing. It's made in the USA, which matters when you're counting on your gear in the field.
If you've been looking for a no-nonsense way to attach a quality sling to your AR without adding bulk or complexity, the RSA checks every box. It works with any Picatinny rail, plays nice with standard clip-in systems, and won't let you down when you need it.
