Magpul MAG516-COY MS1/MS3 Sling Adapter - Steel, Coyote Melonite Finish, Polymer Hardware, Nylon 1.25" Webbing, Two to One-Point Design for AR-15, M4 & M16

The Magpul MAG516-COY MS1/MS3 sling adapter gives AR-15, M4, and M16 shooters the flexibility to run their rifle in either two-point or one-point configuration without swapping hardware. Built from Melonite-finished steel paired with reinforced polymer hardware, this adapter is designed to handle the durability demands of the range, hunt, or duty work while resisting corrosion in field conditions. The system works with Magpul's MS1 sling and Paraclip to enable quick conversion between carry modes—a real advantage when you need to shift from a stable two-point setup for precision shooting to a single-point rig for faster movement through brush or barriers.

The hardware itself is intentionally lightweight, so adding this adapter doesn't create unnecessary bulk or weight budget creep on your rifle. The snag-free webbing design keeps the 1.25" nylon strap from catching on gear, clothing, or magazine pouches when you're moving through tight spaces or working around obstacles. That attention to detail makes the difference between gear that disappears when you need it and gear that gets in your way.

Made in the USA, this adapter is the kind of no-nonsense accessory that earns its place on a rifle through reliability, not marketing hype. If you already run Magpul slings or are building a modular sling system, the MAG516-COY delivers the convertibility to match how you actually shoot.

Frequently Asked Questions

Will the MAG516-COY work with other sling brands?

This adapter is designed to work with Magpul's MS1 sling and Paraclip system. Compatibility with other sling brands depends on their attachment design—consult the specific sling's documentation.

What's the difference between this and just buying a one-point sling?

The MAG516-COY gives you both configurations from a single sling. Combine it with an MS1 sling and Paraclip to convert between two-point (for stability and control) and one-point (for faster transitions and close-quarters work) without carrying multiple slings.

What's included in the box?

The listing covers the adapter itself. To use the full two to one-point system, you'll also need a Magpul MS1 sling and Paraclip, which are sold separately.

Is this sling adapter corrosion-resistant?

Yes. The steel components feature a Melonite finish, which provides extreme resistance to wear and corrosion—suitable for field and outdoor use.
