The closest thing I can find are the side+top picatinny rails that attach to the side mount like this: I've found 5-6 different brands that make them and none of them say the iron sights are still visible and they look like they'd be too high for a cowitness. I think a rail on the gas tube would be just as useless because of the way the sights are on the AK. I guess BIUS aren't absolutely essential, but I'd like to make this my HD weapon for now (it's either this or a 10/22.) I trust eotech enough to work when I need it to, but I'd just feel more comfortable with a cowitness just in case something fucked up happens. Maybe it would be sufficient enough just to have the quick-release so I could at least ditch the eo in a hurry and switch to irons. What are your opinions? Also mine is a WASR-2, I'm assuming most of these rails are compatible with the mount mine came with, am I mistaken?
