Kalashnikov-Koncern

Are the small arms of ISIS in Iraq mostly stock that’s been in country for a while (former stores of saddam’s various Romanian and Hungarian Kalashnikov orders and Iraqi produced tabuks.) and things captured during the Iraqi army’s retreat; or is there a large amount of small arms coming in from other places?

Thanks for the response, I was interested in it after seeing some older stuff like FALs, as well as what I suspect are Libyan Contract Ak103s, I was wondering if these different but sympathetic groups around MENA do any form of trading or buy from the same arms dealers.
