The AKKS rifle is documented in the 2011 Syrian Civil War through Conflict Armament Research's April 2015 field dispatch on weapons and ammunition captured from Islamic State forces in Kobane. CAR reported that Kurdish People's Protection Units captured Islamic State weapons during the September 2014-January 2015 battle, and that CAR investigators worked with the YPG in Kobane from 20 to 27 February 2015 to document the recovered materiel.
Within the Kalashnikov-pattern assault-rifle section, CAR recorded 280 rifles captured from Islamic State forces in Kobane. The report identified 22 of those rifles as Bulgarian-manufactured and included a photographed example captioned as a Bulgarian AKKS assault rifle in Kobane, Syria, in February 2015.

Timeline
Islamic State forces laid siege to Kobane from 13 September 2014 until their retreat from the city on 26 January 2015. CAR's dispatch treats the documented weapons as materiel captured from Islamic State forces during that battle, not as a general inventory of every faction in Syria.
Between 20 and 27 February 2015, CAR investigators documented remaining captured materiel in Kobane. By then, CAR noted that the YPG had already integrated much of the seized materiel into its own stockpiles or deployed it elsewhere, which limits the record to the items CAR could inspect and photograph.

Narrative
The AKKS appears in the Kobane record as one member of a mixed Islamic State Kalashnikov inventory. CAR reported that the rifles it documented came from several manufacturing countries, with China and Russia accounting for half of the 280 Kalashnikov-pattern rifles and most of the rest coming from Eastern Europe. Bulgaria accounted for 22 rifles in that sample, and the AKKS example was one of the Bulgarian weapons illustrated.
The evidence supports Islamic State possession of at least one Bulgarian AKKS rifle in the Kobane battle context. It does not establish the rifle's supply route, whether that specific rifle was fired during the siege, or whether AKKS rifles were routinely issued across Islamic State units in Syria.
The weapon identity matches the Bulgarian AKK/AKKS designation family: Armedconflicts.com identifies the AKKS as the folding-stock version of the Bulgarian AKK, while Modern Firearms places Bulgarian Kalashnikov production in Arsenal's Kazanlak lineage. Those background sources support the rifle designation and origin, but the conflict-use claim rests on CAR's Kobane field documentation.
