I have my eotech 512 zeroed on my AR15, it is mounted in rail slot T-12. If i were to move it forward about 2 slots to T-13 or T-14 would it lose zero or not be hitting the exact same as it was? Any help is appreciated
It will probably be closer than if you took a new one out of the box and put it in the new position, but will need re-zeroing or at least checking zero.
It will more than likely need a couple of clicks adjustment. I had to adjust mine 3/4" at 100 yards after moving mine forwards a couple of slots to make room for a magnifier.
How much it will be off will depend on how warped or not straight your upper receiver is. They are have variances, some more than other. I have a Daniel Defense upper on one of my builds and I can move the scope at will with no appreciable change in the POI. I don't know if all DD uppers are like this or if I just got lucky.
I also have a Rock River upper and if I change the position of the scope, the POI will be off by about an inch. I guess it varies.
