Amnesty International's 2015 report on the arming of Islamic State, drawing on Conflict Armament Research field work and other weapons analysis, identifies the modern Russian AK-74M among small arms in evidence with IS forces in Iraq and Syria. The report states that IS mainly used AK-family rifles and that the AK-74M was most probably looted from Syrian army stocks.
The same report treats the AK-74M as part of IS-held small arms rather than as a documented foreign transfer package to the group. It also notes that precise chains of custody, weapon quantities, operational condition, and the group's ability to deploy more sophisticated weapons could not be verified from the available conflict-zone evidence.

Timeline
In 2014, Conflict Armament Research documented weapons and ammunition captured from Islamic State forces in Iraq and Syria, providing part of the field-research base later cited by Amnesty International for IS weapons holdings. CAR's later three-year investigation states that its teams analyzed materiel recovered from the group from 2014 to 2017 in Iraq and Syria.
In December 2015, Amnesty International published its IS arms report and identified the AK-74M in evidence among the group's AK-pattern rifles. The report connected that particular modern Russian rifle to probable looting from Syrian army stocks, placing it in the Syrian Civil War as captured or diverted infantry small arms.

Narrative
The Syrian Civil War evidence for the AK-74M is strongest as captured-equipment and insurgent small-arms documentation. The sources do not identify a specific AK-74M firing incident, unit roster, or battlefield date in Syria; instead, they document the rifle type in IS-related evidence across the Iraq-Syria theater and assess a probable Syrian army stock origin.
Within that evidence set, the AK-74M's role was the same basic infantry role as other AK-family rifles: a shoulder-fired assault rifle used by irregular forces that relied heavily on captured state arsenals. CAR's later regional study found that AK-pattern assault rifles and Warsaw Pact calibers dominated the weapons and ammunition recovered from IS forces, which is consistent with the AK-74M appearing as one rifle type inside a broader captured small-arms pool.
