The Magpul MS1 QDM Sling takes the versatility of the original MS1 sling to the next level by integrating factory-installed Magpul QDM quick disconnect swivels. This enhancement features a robust design, providing a superior alternative to traditional push button swivels. The Magpul QDM boasts a low-profile configuration, allowing for one-handed operation, and is finished with a corrosion-resistant Melonite coating. Its high-strength, rotating bale ensures the sling webbing is canalized, preventing rollover and tangling. This advanced sling system is optimized for dedicated two-point sling use, built around the intuitive MS1 Slider. The MS1 QDM Sling offers rapid adjustments to lengthen or shorten the sling effortlessly, without any slippage or snag hazards. As a two-point sling, it facilitates smooth shoulder transitions and quick adjustments for hands-free rifle carry and shooting support from various positions. For those seeking one-point sling functionality, adapters from the MS3 and MS4 Slings (sold separately) can be used. Engineered for durability, the MS1 QDM Sling passed extensive testing, enduring tens of thousands of cycles in wet, dry, and sandy conditions. It also survived static-load testing without slippage for 72 hours and sustained six-foot dynamic drop tests. Our field testing included swimming, jumping, hunting, hiking into the mountains, and rigorous shooting scenarios in rugged environments, confirming its reliability and resilience in various harsh conditions.
