Magpul Industries MAG519-COY MS1/MS4 Adapter Coyote Melonite Steel Nylon Webbing

The Magpul MAG519-COY MS1/MS4 Adapter quickly converts an existing Magpul MS1 Sling into a fully convertible sling system. When paired with the MS1 Sling and a QD Sling Swivel (MAG540), this adapter provides fast, tool-free switching between one-point and two-point carry configurations.

Built around a heavy-duty push-button QD Sling Swivel for one-point attachment and an ambidextrous QD shackle for two-point use, the adapter delivers reliable weapon retention with quick-release capability in an emergency. The hardware is constructed from Melonite and manganese phosphate finished steel for outstanding wear and corrosion resistance, paired with custom 1.25" snag-free nylon webbing that is strong, wear-resistant, and chafe-resistant.

The colored webbing receives a Near Infrared (NIR) treatment to reduce IR signature, making this adapter well-suited for low-visibility and tactical environments. Rear mounting is compatible with any receiver, end plate, or buttstock that accepts a push-button QD socket, and the ambidextrous design supports both left- and right-handed shooters. Proudly designed and manufactured in the USA.
