The FN40 Enhanced Grenade Launching Module is a 40mm underbarrel grenade launcher originally designed by the Belgian arms manufacturer Fabrique Nationale for the FN F2000. The EGLM was later modifed for use by the US military with the FN SCAR assault rifle. The weapon has a double action trigger, giving it the advantage over the M203 Grenade Launcher in that it does not have to be re-cocked if the grenade misfires.
