The Magpul MS1/MS4 Stealth Gray Sling Adapter gives you the flexibility to run your rifle in either two-point or one-point configuration without swapping gear. Built for AR-15, M4, M16, and AK-platform rifles, this steel and polymer adapter bridges the gap between different sling systems—pair it with an MS1 Sling and QD Sling Swivel to unlock convertible carry options that adapt to your shooting style, whether you're hunting, running drills at the range, or training in the field.
The adapter uses Melonite and manganese phosphate finished steel for corrosion resistance and durability under hard use. The custom-designed 1.25" nylon webbing is engineered to be snag-free, so it won't catch on gear, clothing, or optics when you transition between shooting positions. Magpul's polymer hardware keeps the overall weight down without sacrificing toughness—this is gear built to work, not to impress. Made in the U.S.A., it's designed to pair seamlessly with Magpul's modular sling ecosystem.
If you run multiple rifles or like to tune your setup as conditions change, the two-to-one-point conversion capability means you don't need duplicate slings. The quick-release mechanism lets you drop to a true one-point rig in seconds, then transition back to two-point stability when you need it. It's the kind of practical modularity that makes sense in the field.
