Thx - Yes, it has the BDC3 reticle. I was concerned about zero because of the distance between the barrel and scope center. I tried to find info on zeroing an optic on the m16a1/2 carry handle thinking that would provide a zeroing distance. But nothing came up.Looks like you might have the BDC3 reticle if it's a new 1? Usually, the center dot is at 100 yards and above the dot is for 50-7 yards depending on which part of the arch your aimpoint is at. Maybe this will help some.
