Just got mine yesterday and mounted it on my 6mmAR. It's to low and I have to smash my face against the stock to see through it. I have a High end rail riser coming to bring it up 1/2". For someone that has MK3 or MK2 that has mounted theirs on a bolt gun, was there any problems in the height or getting the scope back far enough to be usable and comfortable? Thanks!
