I got the Leupold 3-9x32 EFR. Excellent glass. Thought might have some problems with light transmission because of the small objective, but it's very bright. And when using the turrets to switch from 20yd zero to 50, it goes right back to where it's supposed to. It wasn't cheap, but when I scope a gun, I don't think it should ever need replacing. My only complaint is I wish it had Mil dots or hash marks for holdover.
