I don't like running AK optics off of dust covers. It probably works well for some guys, but I don't see it working for me. My rifles get bounced around a lot.
Zastava hooked me up with their ACOG mount and an offset RMR. Looks good. Solid.
They say the 3x TA-50 was made specifically for an AK. I was going to pull the trigger on one, but I've never saw one in person and that bugged me a little... I get ya on eye relief, but Trijicon's eye relief numbers are alway way underestimated in their published material. I saw a TA44 on one and it got me thinking that I should review all options.
