The A1/A2 Buttstock Adapter (A2B) provides an ambidextrous connection point on the top of M16/AR15 A1, A2, and A4 buttstocks. The A2B brings the sling attachment point to the top of the weapon, reducing the tendency for the weapon to flip upside down when slung. It works best when paired with the Vickers Sling.
