I am torn between one optic and another for my AK. I would like something good that is low profile and doesn't take up much space (not the bulky) and is good like a reflex sight perhaps since they're very thin. Does anybody have a good recommendation for a good optic? And how much do they go for? I can only put it on top of the hand guard area above the gas tube because thats where the rail is. Is this a good location also? Thank you! And merry Christmas.
