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

The Magpul MAG516-BLK MS1/MS3 sling adapter is a versatile steel connection point built for AR-15, M4, and M16 platforms that gives you real flexibility in how you configure your rifle. Unlike all-in-one sling attachments that lock you into one setup, this adapter ships without connecting hardware—that's intentional. You pick the hardware (Paraclips, push-button QDs, or one-point adapters sold separately) that matches your actual shooting needs, whether you're running a two-point tactical setup for patrol work, hunting, or sport shooting, or converting to a single-point configuration for CQB or vehicle work.

Built from steel with a Melonite-finished surface that resists corrosion and wear, the MAG516-BLK handles rough field conditions without flinching. The sling webbing is nylon, 1.25 inches wide, designed with snag-free edges so it won't catch on gear, clothing, or your rifle's furniture during transitions. Magpul's polymer hardware elements keep weight down without sacrificing durability. U.S. manufacturing means consistent quality and supply you can count on.

This is the adapter for shooters who don't want to be locked into one sling philosophy. Whether your rifle needs to transition between roles—duty to training to hunting—or you simply prefer to dial in your own hardware preference, the MS1/MS3 gives you the foundation and then trusts you to finish the job the way that works for your gun.
