Made in the USA, the MS4 can quickly switch between one-point and two-point configuration. It features two heavy-duty push-button QD Sling Swivels along with a custom steel connection ring to allow one to two-point convertibility. This modification allows compatibility with QD sling cups commonly found on lower receivers, receiver end plates, buttstocks, and many low-profile forward QD Sling Mounts. The MS4 Dual QD GEN2 is finished with Melonite for extreme resistance to wear and corrosion, and colored webbing has Near Infrared (NIR) treatment to reduce IR signature.
