Filling the same mission requirement as the standard MS3 , and now with the MS1 slider, the MS3 QD can quickly switch between one-point and two-point configuration. The MS3 QD maintains material construction and specifications identical to that of the standard MS3, but features a heavy duty push button QD sling swivel for the one-point (rear) weapon attachment rather than the Magpul Para-clip found on the standard MS3. This modification allows compatibility with QD sling cups commonly found on lower receivers, receiver end plates, and butt stocks.
