I don't have that Mount, but I do have that particular Scope. Both combined for that price is a really good buy.
The Glass is crystal clear edge to edge. The magnification ring is a little stiff, but find the power you want, it won't move by itself under any recoils. The Adjustment Turrets have good "positive" clicks. I haven't used the drop marks yet, so don't know how well they work, but they're set up with using 223/5.56-55gr bullets that are commonly found on shelves. I don't remember if the Turret Knobs are resettable, it's been a while since I had the Rifle out that has this Scope on it.
EDIT: OK, looking at a close up of the Scope, it does appear by removing the set screw on the Turret and lifting up the Turret, you can reset back to Zero.
