Scopes on AKs are not extremely common...grenade launchers are, honestly about 30% of the guys you see in Chechnya photos have launchers on their 74s - they say they use the hell out of them.
The scopes you will see are on the dragunovs obviously, or will be special purpose (ie. nightvision) scopes, like the one above and this one
(1985 era AK-74 w/ night scope)
If you are going to use a scope, then make sure to use a new gun, an old school AK would look out of place - units like Spets etc. have access to the newest guns (like GG RK-103/104, CA SLR-105) etc. The new "all black" rifles which are the latest incarnation of their weapons.
I still think it looks dumb...but they do use them. To me? You sound like a clost M4 lover if you want scopes, and lasers and stuff
if you want tips on making an AK variant look realistic - go to
www.red-alliance.net for weathering techniques, and lists of real mods (like blue electrical tape around magazines, how to make "royal" magazines, and how to put compression bands around your rifle butt!)
ps: see where I got my inspiration for my rifle?
