Direct proof of use
WIRED reported in May 2013 that M40 106 mm recoilless rifles were appearing in the Syrian war after previously showing up with Libyan rebels. The article described the Syria examples as long-tubed guns mounted on jeeps or pickup trucks and used against bunkers, fortified positions, sniper locations, and tanks.
Oryx later identified a 106 mm M40 recoilless rifle among rebel fire-support weapons used during the 19 January 2020 attack on Abu Dafna in Idlib Governorate. That account places the M40 alongside mortars, artillery, rockets, and technicals in the rebel attack package.

Timeline
The first dated public source used here is WIRED's 31 May 2013 report, which treated the M40 as a recurring visual feature in Syrian battlefield videos and attributed the known Syria examples to rebel hands. The report also said provenance was unresolved, with possible links to Libya, Western arsenals, Libyan transfers, or Iranian-origin Anti-Tank Gun 106 production.
The 2020 Oryx account gives a later incident-level example. In the Abu Dafna attack, rebel forces used the M40 in a broader fire-support package before armored and infantry elements advanced on government positions.

Battlefield role
In opposition service, the M40 filled a direct-fire role that matched the weapon's older anti-armor and bunker-attack design. The available sources show it mounted on light vehicles and used as a support weapon rather than as a mass-issued infantry arm.
The sources separate use from provenance. WIRED directly supports rebel possession and battlefield use in Syria, but it did not settle whether the guns came through Libyan rebel stocks, Western-supplied channels, Syrian government capture, or Iranian-pattern production. Oryx supports later use by Idlib rebels in one documented attack, but it does not establish a complete inventory or chain of custody.

Evidence limits
The public source package supports M40 use by opposition and anti-government forces in the 2011 Syrian Civil War. It does not support a precise count of rifles, a complete list of operating factions, or a settled supply route into Syria.
