Description
The Magpul MS4 Dual QD Sling GEN2 is a convertible sling that switches between one-point and two-point configuration with one hand, using push-button QD swivels at both ends. The MS1 slider adjusts length while keeping tension, so the rifle can be cinched in or let out without loosening buckles. It attaches to any push-button QD socket on lower receivers, end plates, buttstocks and forward mounts. Specifications from Magpul: 48 to 60 in overall length with ±5 in adjustment, 10 in slider range, 1.25 in custom nylon webbing with Near Infrared (NIR) treatment, and a precision-cast steel QD D-ring with QPQ salt-bath nitride finish. Made in the USA and 100 % Berry Amendment compliant.
