When mounted on the rifle, the EGLM has its trigger located underneath the trigger of the assault rifle, which negates the need to alter grip significantly. In this set-up, the trigger can be operated by the middle finger of the firing hand without moving it from the pistol grip of the rifle. It is a fully ambidextrous design and isn't required to be cocked before each shot. This ambidexterity also includes a canting barrel to facilitate loading from either side of the weapon.
The FN EGLM can also be mounted on a standalone frame with the simple change of its trigger pack module. This allows the launcher to be mounted, complete with sighting systems on a accessory-compatible frame. In this format, it is known as the Mk13 Grenade Launcher.
