Ok so I have had a chance to play with the mk8 for a week or so now, overall I like the locking turrents, zero stop and the glass in the scope.....I mounted itin badger medium rings and have plenty of room on a medium Palma barrel contour. I'm not too thrilled about the MTC feature and find it hard to dial either 5.1 or 4.9 and you have to reposition your hand to keep the dial turning. It seems to track perfectly and almost no tunneling on the lowest power, very very slightly but not a big issue for me.
I'm also not too thrilled about the H-58 reticle and will plan on shipping it back for a TMR once it's available, in short I really like the scope but am not thrilled about the reticle, I have been shooting the TMR for so many years its just different at this point.
Overall fit, finish and quality appear excellent.
