The Magpul MAG516-RGR MS1/MS3 sling adapter gives you the flexibility to run your AR-15, M4, or M16 in either two-point or one-point configuration without swapping hardware. Built from Melonite-finished steel with reinforced polymer hardware, this adapter pairs with the MS1 sling and Paraclip to let you convert between setups quickly—essential if your mission changes from controlled range work to dynamic close-quarters carry. The 1.25" nylon webbing resists snagging and stands up to rough handling in the field.
Magpul designed this piece for shooters who demand durability without excess weight. Whether you're a tactical rifle competitor, a patrol officer, or a hunter managing multiple carry positions, the adapter's snag-free geometry and corrosion-resistant finish mean it'll stay put and work reliably regardless of weather or terrain.
Made in the USA, the MAG516-RGR is the kind of simple, proven accessory that doesn't grab headlines but absolutely earns its place on a serious rifle. If you're already running an MS1 sling and want to add one-point versatility, this adapter does the job without breaking your kit's flow.

Frequently Asked Questions
What sling and hardware do I need to use this adapter?
The MAG516-RGR works with the Magpul MS1 sling and Paraclip to provide two-to-one-point convertibility. The adapter alone handles the attachment point; you'll need those components to complete the system.
Will this work on my AR-15, M4, or M16?
Yes, the adapter is compatible with AR-15, M4, and M16 platforms.
How durable is the Melonite finish?
Melonite is a case-hardening process that delivers extreme resistance to corrosion and wear, making it ideal for field use in wet, humid, or saltwater environments.
Is this adapter light enough for tactical use?
Yes. The combination of steel with reinforced polymer hardware is designed to be lightweight without sacrificing durability, making it suitable for duty and tactical applications.
