Thank you all for your help.
All rifles appear to have the same configuration except for their muzzlebrakes.

I'm guessing they are all customized Izhmash AK 103's. They are a bit too expensive for Kurdish insurgents who have been causing trouble in south east Turkey(near Northern Iraq) for the past couple decades. Thousands of these insurgents have been neutralized and their weapons captured but never anything this fancy. Mostly ex Soviet AK47's, SVD's RPG7's and sometimes a few M-16's. (possibly Vietnam era M-16's)

Northern Iraq which is populated mainly by Kurdish Iraqis, has been out of control for some time now. Illegal arms dealing, smuggling narcotics and also oil is a part of every day life in that region. Due to its geography which is mountainous, neither the multi-national force in Iraq nor Turkey is able to control these illegal activities. And they are escalating steadily.
