The Magpul MS1 MS4 Adapter converts an MS1 sling into an MS4 configuration, letting you switch between one-point and two-point carry on the fly. That flexibility matters more than it sounds: a two-point sling is far better for carrying a rifle over distance, while a one-point lets you transition and move quickly in tight spaces.

The adapter uses a QD swivel for fast attachment and detachment from a compatible socket, and the paraclip-style hardware is built from steel for strength. This one is finished in Ranger Green. If you already run the MS1, this is the small part that makes it two slings instead of one.
