Lately Ive been buying Zeiss scopes ( GREAT scopes BTW) but on this 25-06AI that Ive been working up I wanted something different but didnt want to break the bank either...mainly because I was trying to get this thing put together as cheaply as I could. I went with a Nikon 4.5 x 14 x 40 Side focus model...and bottom line is Im Impressed! VERY clear scope. After getting it sighted in today I did some ring arounds to see if it tracked..I think its called...and sure enough it came right back to home plate. I bought it off of E-bay for less than 200 and Im glad I got it now!
