DevDroid's electric trigger for the Mk-19 grenade launcher is a Ukrainian remote-firing actuator for 40 mm automatic grenade launchers in combat modules and turrets. It sits at the final mechanical step of a remote fire-control chain, physically actuating Mk-19, AGL-53, or RDS-40 launchers after a command from a robot, vehicle, or fixed weapon station.
In the 2014 Russia-Ukraine War, Ukrainian technology reporting says DevDroid electric triggers are used in remote fire-control systems on ground robots, armored vehicles, fixed combat modules, and anti-aircraft turrets; the 40 mm launcher version is listed for Mk-19, AGL-53, and RDS-40 integration.
Role detailsThe trigger is a small actuator in a larger remote weapon-control loop: the operator or control system sends a fire command, and the electric trigger physically trips the launcher trigger at the weapon.
| Topic | Source-backed detail | Reader context |
|---|---|---|
| Supported launchers | DevDroid and Ukrainian reporting list Mk-19, AGL-53, and RDS-40 automatic grenade-launcher compatibility. | The catalog links the existing Mk-19 / 40 mm family page and the AGL-53 record; RDS-40 is kept as an unlinked compatibility item because no matching public catalog record exists. |
| Remote-fire role | dev.ua describes electric triggers as the physical trigger element in remote fire-control chains. | This makes the component operationally important even though it is not a standalone weapon. |
| Platform contexts | dev.ua lists ground robots, IFVs, APCs, armored combat vehicles, fixed combat modules, and anti-aircraft turrets. | Those are product-family deployment contexts, not separate confirmed mounts for every individual trigger unit. |
| Installation and conditions | Mezha reports installation without structural weapon changes and operation under vibration, dust, moisture, and temperature variation. | The component is built for field integration into remote weapon stations rather than bench-only testing. |
DevDroid's electric-trigger line separates heavy-machine-gun and automatic-grenade-launcher trigger units by the weapon family they actuate.
| Variant | Configuration | Designation notes |
|---|---|---|
 | 12.7 mm heavy-machine-gun trigger | DD-M2-S1 is the adjacent DevDroid electric-trigger model for Browning M2-family heavy machine guns, while this entry covers the 40 mm Mk-19 / AGL-53 / RDS-40 launcher trigger.
