no cant up,

built on the centerline to minimize the built in aiming errors.

and now that it's a computer sight, range and windage doesn't matter. T.O.T is the key.

Old days, it was sighted for a 4k no wind shot....down low, rarely went up to such a high altitude back then. Shoot, 30 degrees is just over a mile up. Took special oxygen to get that high back then
