Filling the same mission requirement as the standard MS3 Sling, the MS4 can quickly switch between one-point and two-point configuration. The MS4 maintains material construction and specifications identical to that of the standard MS3, but features two heavy-duty push-button QD sling swivels rather than the Magpul Paraclip aling with a steel D-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, including the Magpul RSA-QD. The MS4 Dual QD incorporates a new low profile quick-adjust Slider which minimizes bulk and allows for secure, yet effortless, sling adjustment. Webbing length has also been increased for a comfortable fit with all body types and armor configurations. Made in U.S.A. and 100% Berry Amendment compliant.FEATURES: Heavy-duty push-button QD sling swivels for both one and two-point attachment Durable, precision-cast steel QD D-Ring allows for quick transition from one to two-point mode and is finished with Melonite for extreme resistance to wear and corrosion Custom 1.25 inch wide nylon webbing material is strong and wear resistant while remaining anti-chaff for user comfort Low-profile adjustment Slider for adding or removing sling tension in two-point mode with a single-hand Colored webbing has Near Infrared (NIR) treatment to reduce IR signature Sling MountingREAR/FRONT - Compatible with buttstocks, end plates, receivers, and hand guards that have a QD socket as well as the Magpul ASAP-QD, RSA-QD, MSA-QD, and shotgun Forward Sling Mounts
