Is 2.6" the correct measure of the AR15 sight plane (CQ311) HOB?
If so, why does the trajectory for 55gr bullets when modeled in ballistics programs differ so greatly from the <3" deviation from LOS that is written in online forums (for 25yd zero)? Remington Shoot gives closer to a 10" positive deviation.
