I was just now about to purchase a TA31F from Primary Arms but stopped when I saw in the item’s description that this ACOG is calibrated for 55grn rounds. I thought I’d seen on this site and TOS that the reticle was, in fact, calibrated for 62grn rounds (which is what I desire). Could you all confirm for me that 62grn 5.56 is correct? I looked at Trijicon’s site and it wasn’t helpful in this regard.

Many Thanks!
