Well I finally bought a Vortex viper 6.5-20x44 for the 260. The scope seems fairly well built with positive clicks that are repeatable. Overall the scope is very user friendly. But here comes the problem. My Nikon buckmaster 18x is noticeably clearer especially at higher magnification. The viper kind of looks like im looking through a thick milk glass. I know many of you love your vipers and this was a factor in my purchase. To all of you that own one.....does this seem normal? No I haven't talked to vortex yet, just testing the waters.
