Manufacturer: Magpul MAG509-BLK
New from Magpul, the MS4 is the answer to the demand for and all QD swivel and socket sling. The same 1.25 inch wide nylon webbing is back but the clips have been replaced with easy and rugged QD swivels to connect to modern QD AR-15 accessories.
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. 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.
