1) How much do you want to spend and are you concerned with flash suppression or recoil management? Even though its a AR site there is a good list of options here so you can get an idea on price - http://www.bravocompanyusa.com/Flash...ators-s/43.htm
. I just did this and went with a Battlecomp 2.0. List of all I had my smith do here - http://fleetingsurvival.com/2012/10/...art-6-rebirth/
2) If this is a SHTF rifle I think the tritium front sight bar is an excellent idea. I am not a fan of the peep on an AK. My buddy got one and he no longer runs it. If its a SHTF rifle I would recommend a red dot but understand if you are not into that.
