The Magpul MS1/MS4 Sling Adapter is a versatile two to one-point sling conversion tool built for shooters who need flexibility in how they carry and deploy their AR-15, M4, M16, or AK-platform rifle. Whether you're transitioning between precision rifle work and dynamic movement, or you simply want to switch carry modes without swapping gear, this adapter lets you do it fast. The steel construction with QPQ salt bath nitride and manganese phosphate finish resists corrosion in field conditions, while the custom 1.25-inch nylon webbing handles the real-world abuse that comes with hard use.
This sling adapter works with push-button QD (quick-detach) sockets found on most modern receivers, end plates, and buttstocks for rear attachment, and pairs with optional QD Sling Swivels at the front for two-point rigging. The ambidextrous QD shackle design keeps things simple—no fiddling, no tools, just fast, reliable transitions. Magpul engineered the webbing with snag-free geometry and included near-infrared (NIR) treatment to reduce signature if that matters for your application. Everything is made in the USA and built to work hard.
Pair it with an MS1 Sling and compatible QD swivels to unlock the full two to one-point system, or use it as a quick upgrade to your existing sling setup. If your rifle already has QD sockets installed, you're ready to go. This is the kind of tactical accessory that pays for itself the first time you need to shift from two-point carry to single-point deployment without breaking stride.

Combine this adapter with an MS1 Sling and optional QD Sling Swivels. Use the adapter at the rear of the rifle (on the buttstock or end plate QD socket) and attach a QD swivel at the front for two-point rigging, or remove the front attachment for one-point carry.
Yes. The QPQ salt bath nitride and manganese phosphate finish provides solid corrosion resistance, and the nylon webbing is designed to be wear-resistant in field use.
