I am fixing to buy an ATPIAL-C and I was wondering how much, if any, of the device blocks the lower portion of the sight picture inside of a standard TA-31 ACOG mount? Does anyone have this setup that could post a pic? I have a Unity dual switch mounted at the 12-o’clock and when my thumb is on this switch, I can just barely start to see the top of my thumb in the optic. It doesn’t bother me, however it did raise the question on how much taller the ATPIAL is/may be. Thanks.
