Magpul - MS4 QDM Dual QD Sling One-Point / Two-Point

One Sling. Two Configurations. Zero Compromise.

The Magpul MS4® QDM Sling builds on the proven MS4 Dual QD Sling GEN2 by adding factory-installed Magpul QDM quick-disconnect swivels for faster manipulation, enhanced durability, and superior security. Designed for rapid transition between one-point and two-point configurations, the MS4 QDM Sling is ideal for duty, defensive, and preparedness-focused rifle setups.

The Magpul QDM is a heavy-duty evolution of the traditional push-button QD swivel, featuring a low-profile design, single-handed operation, and a high-strength, freely rotating steel bale that prevents sling webbing rollover. Finished with a corrosion-resistant QPQ salt bath nitride treatment, the QDM hardware is built to withstand hard use in harsh environments while remaining fully compatible with standard QD sling cup interfaces.

• Factory-installed Magpul QDM swivels for rapid one-point and two-point conversion
• QPQ salt bath nitride finished steel swivels and D-ring for extreme wear and corrosion resistance
• Freely rotating QDM bale canalizes webbing to prevent rollover
• Low-profile MS1® quick-adjust slider allows fast, secure length adjustment
• No loose tails, loops, or snag hazards
• Reinforced polymer slider and tri-glides reduce weight while maintaining strength

Comfort and Signature Management

• Proprietary 1.25" tubular nylon webbing for strength and abrasion resistance
• Anti-chafe construction for extended wear and use with body armor
• Near Infrared (NIR) treated colored webbing helps reduce IR signature
