I think many of us have the same problem, myself included. I went with the "retro style", and bought a NcStar Coly copy. It zeroed ok, but there were no positive clicks on the adjustment, and the reticle was too big for the target. It covered the 10 ring at 100 yds. I think, IMHO, go for the more modern approach. Nikon makes decent scopes that won't break the bank. Redfield has some American made scopes that are reasonable too. There's one thing I can't stress enough. Don't skimp on the mount and buy Chicom junk. I did that very thing and wound up throwing it out. It was machined cockeyed. I couldn't get cross hair alignment. I know the scope is fine, because I took it off my M4gery. I bought this Smith Enterprises mount of the EE for 10 bucks. They go for 60 - 95 new on the net, last I looked, so I got lucky. The quality compared to the Chicom is night and day.
Let us know what you decide.
