Expect that the scope will have next to zero for parallax correction and will be fuzzy at 3/4 to full magnification. Also, expect it to fail the box test. I had one for a while on my 7mm-08 till I got fed up with wandering zero and fuzzy optics and a side focus that did nothing so I threw it away and put on a used Leupold 8x40AO scope. That 25+ year old Leupold blows away the Chinese scopes...
