Armament Research Services documented the Chinese QLZ87 automatic grenade launcher in the Syrian Civil War in its August 2014 Arms & Munitions Brief. The brief identifies the QLZ87 as one of the uncommon small arms and light weapons that appeared with anti-government rebel groups and the Syrian Arab Army, and its photo list includes an anti-regime rebel combatant in Syria armed with a QLZ87 in light configuration.
Amnesty International's December 2015 report on Islamic State arms, drawing on ARES analysis of photos and video, separately notes that QLZ87 launchers had been observed in Syrian conflict imagery with armed opposition groups and Islamic State fighters. Together, the sources support fielding by opposition and jihadist actors in the Syrian conflict, but they do not establish a verified firing incident, a complete delivery chain, serial-number trace, or the number of launchers in Syria.

Timeline
The dated public record begins with the conflict-period imagery assessed by ARES before August 2014. ARES used that imagery to document an anti-government Syrian rebel combatant carrying the launcher in light configuration and to list Syrian rebel forces among non-state armed groups known to have held the QLZ87.
In December 2014, ARES again referred to the QLZ87 as documented in non-state armed-group hands in Syria while discussing a separate Kurdish-force sighting in Iraq. In December 2015, Amnesty published its ARES-backed assessment that QLZ87 launchers had appeared in Syrian conflict photos and video with armed opposition groups and IS fighters.

Battlefield role and sourcing limits
The QLZ87's supported Syrian-war role is light infantry fire support in non-state armed-group service. ARES describes the launcher as a 35 x 32SR mm selective-fire weapon that can be fired from a bipod in light configuration or from a tripod in heavy configuration, with a lighter man-portable role than heavier automatic grenade launchers such as the Mk 19 or AGS-17.
The available Syria-specific evidence separates fielding from transfer certainty. ARES later wrote that Qatar was believed to have supplied Syrian rebel forces with Chinese weapons procured from Sudan, including the QLZ87, but framed possible acquisition routes for Kurdish examples as unclear. This usage record therefore treats the Syrian evidence as documented possession or fielding by armed opposition and Islamic State-aligned actors, not as proof of a settled transfer route.
