my two tops are the : 1. Krebs rear peep and the XS 24/7 front sight post still allows for yardage adjustments and easy front sight acquisition.
2. tech sights-- i just put them on my 10/22 and would have them on my saigas except there is no quick yardageadjustmentt. yes they do have one now that you candiall in at various distances. I like the quick slide rear leafadjustmentt. No it is not exact and most of the time you will use battle sight zero but when you know your distance or can gauge then it is nice to have the ability to help get you close quickly..
