Quickly reconfigurable between 1-point and 2-point operation, the Magpul MS4 QDM Sling enhances the proven MS4 Dual QD Sling Gen2 by including factory-installed Magpul QDM quick-disconnect swivels. As a heavy-duty replacement for the typical push-button swivel, the Magpul QDM offers an innovative low-profile design, 1-handed manipulation, a superior corrosion-resistant Melonite finish, and a high-strength, freely rotating bale that canalizes sling webbing to prevent rollover. This sling system not only provides the strength, speed and security of Magpul QDM hardware, but also maintains compatibility with the standard QD sling cup interface found on many handguards, lower receivers, receiver end plates and buttstocks. Based on the streamlined 1-point MS1 Sling adjustment system, the Magpul MS4 QDM Sling retains the low-profile quick-adjust slider which minimizes bulk and allows for secure, yet effortless adjustment. Webbing length is optimized for a comfortable fit with all body types and body armor configurations. The Magpul MS4 QDM Sling is made in the U.S.A. and is fully Berry Amendment compliant. Features: Factory-installed Magpul QDMs allow rapid conversion between one and 2-point configurations Swivels and D-ring are constructed of Melonite finished steel for strength and extreme resistance to wear and corrosion Secure and rapid length adjustment with MS1 slider No tails, loops, or other potential snag hazards Lightweight, yet durable slider and buckle hardware made of reinforced engineering polymer Proprietary weave, 1-1/4 inches wide nylon webbing is strong and abrasion resistant while tubular construction provides anti-chafing user comfort Colored webbing has near infrared (NIR) treatment to reduce IR signature
