Magpul MAG540 QD Sling Swivel 1.25" Push Button Black AR-15

The Magpul MAG540 QD Sling Swivel delivers rapid sling attachment and detachment with its precision-engineered push-button mechanism. This manganese phosphate finished swivel mounts to any standard 1.25" quick-detach socket, providing instant tactical flexibility for AR-15, M16, and M4 platforms.

What Makes This Different

Unlike basic sling attachments that require threading or complex installation, the MAG540 features a spring-loaded push-button system that engages and releases with audible confirmation. The manganese phosphate coating provides superior corrosion resistance compared to standard black oxide finishes. Machined from hardened steel rather than cast components, this swivel withstands repeated cycling under stress without wear or failure.

Key Features

• Push-button quick-detach mechanism with positive engagement feedback
• Manganese phosphate finish resists corrosion and wear
• Hardened steel construction rated for 300+ pound working load
• 1.25" diameter fits standard QD sockets on rails and stocks
• Low-profile design prevents snag on gear and clothing
• Compatible with AR-15, M16, M4, and similar platforms
• Ambidextrous operation for left and right-handed users

Field performance remains consistent across temperature extremes and environmental conditions. The precision-machined tolerances ensure smooth operation after thousands of attachment cycles. Law enforcement and military units rely on this swivel for rapid transitions between carry positions during dynamic operations. The positive lock mechanism prevents accidental release while maintaining quick access when needed.
