However comma I have had zero shift when I was not being a moron as well. I was trying to pick up on a pattern on this but I was unable because I did not shoot it enough. I don't have a huge amount of experience with the 145 as we only had them for a year before I left my last unit and we use machinegun ACOGs or CQB short dots in my new unit.

I cut your original post up some. No offense please.
I have found that magnified optics with no parallax adjustment aren't parallax free -- no matter how much a company may claim otherwise. Check out the parallax on ACOGs, MGO's, Leupolds that lack a parallax adjustment -- any optic lacking this feature -- and you will see significant parallax issues unless you keep your eye in the exact same spot when looking through such optics.
I have found this to be the majority of a zero shift problem with these low powered "parallax free" optics. See for yourself sometime. How much is the shift? Worse case about three minutes.
Also, the MGO has a feature I personally like but one that can cause problems with guys who haven't yet trained their eyes to see a very consistent sight picture. The MGO has stadia that are broken for the aiming area so a gunner can put his target into the middle of that open part of the stadia. Guys who haven't trained their eyes to see tend to put the target off center in that open area of the reticle -- causing zero shifts. I like it because there is no stadia covering the target but that is me.
Guys will tend to fudge on sight picture with an optic even though they can see the sight picture isn't perfect. The magnification makes them lazy to a degree. Takes about three days to train them out of this condition.
