Hephaestus uploaded photos of a prototype of their AK Rear Sight With rail which can be fitted on both Gas Blowback and AEG AK airsoft guns. According to them, you can use the iron sight area to mount a scope or any weapon accessory you want to mount on it. According to them you can still peer into the scope even wearing a mask which is always a problem when masks are used and you want to use some low profile scope or sight.
