i have the tiapan mounted on my logun solo 177 and love it. the only down side to it for me is the weight it is a bulk but i dnt think i have missed with it yet and its been on for over a year. on full mag i normaly scan the top end of the feilds ( i can see up the feild 500+yard by eye but to see the rabbits and can pick the out easy as 123) i have never noticed a white out even in full mag can see sheep clearly at 2miles ish (from my bedroom window across the other side of the valley)
