I'm using a Leapers 3-9x40 that I bought at a gun show for $80. Lifetime warranty and cheap. I was worried about it holding adjustment, but so far I've put 40 rounds of 270 WSM through the gun with it zero'd in at 100 yards and it still shoots right at about 1". I figure if it lasts me a season or two I'll be happy. Will give me time to save up for a Nikon. Plus, I can have an illuminated reticle in either red or green! lol
