Made in the USA, the MS1 MS3 QD Adapter features a manganese-phosphate finish push-button QD Sling Swivel for one-point attachment, and can be combined with the MS1 Sling (MAG513) and additional Paraclip (MAG541) to provide fast transition between one-point and two-point configuration. It also has a custom 1.25" wide nylon webbing material, and colored webbing has Near Infrared (NIR) treatment to reduce IR signature. For rear attachment it works with receivers, end plates, and buttstocks that have a push-button QD socket for one-point attachment. Snap-hook style sling loops with an inner diameter of at least 3/8" are required, but 9/16" and larger will provide full range of motion of the Paraclip.
