The Tactical Duostock's patented design provides maximum comfort, speed, and freedom of movement for operators wearing body armor in CQB situations. The curved underside is angled so the lower tip rides comfortably on the upper chest or collarbone in a forward, high carry position near the dominant eye; keeps the sights and barrel close to the line of sight, ready to be engaged with minimal head movement. Two models available, one for Mil-Spec M4 carbines. Universal fits aftermarket CAR-15 type buffer tubes. Now available in Desert Tan and Black
