This is the third pattern XM3 Bipod Case for the M3 Bipod. The case is made from cotton canvas and is intended for use with the M-16 rifle. These OD cotton carriers were designed to carry the basic folding M3 bipod and they have the external pocket for cleaning supplies as well as the side pocket with flap meant to carry the three piece cleaning rod (a 4 piece will work as well). We have both G/VG used and EXC condition available. We have one EXC condition with a broken zipper as well.
