The Magpul MAG540-BLK quick detach sling swivel is a push-button QD connection point built for riflemen who need fast, reliable sling attachment without fumbling. This swivel accommodates standard 1.25-inch webbing and connects directly to QD sling attachment points found on most modern AR-15, M16, and M4 platforms. Built from steel with a manganese-phosphate finish, it delivers the durability you'd expect from Magpul—corrosion resistance and a low-profile, tactical look that pairs seamlessly with your rifle's existing hardware.
The push-button mechanism is intuitive: press to detach, release to lock. That simplicity matters when you're transitioning between shooting positions, stowing your rifle in a vehicle, or adapting your carry method on the fly. Whether you're running a dedicated two-point sling with the MS1 or converting between one- and two-point configurations using the MS4 adapter, this swivel serves as the anchor point. It's manufactured in the USA and represents Magpul's no-nonsense approach to rifle accessories—function first, frills nowhere.
If you're building out a rifle sling system or upgrading from older fixed studs, the MAG540-BLK gives you a durable, field-proven attachment point that works with virtually any quality sling designed for QD compatibility. It's a small component with outsized practical value for hunters, tactical shooters, and anyone who runs a two-point system.
