The FN EGLM is an underslung 40mm grenade launcher module which compliments the FN SCAR weapon series, as well as the earlier FN 2000. The most notable feature of this grenade launcher is that, when mounted on a weapon, has its trigger located underneath the trigger of the assault rifle, and therefore 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 doesn't required to be cocked before each shot. This ambidexterity also includes a canting barrel to facilitate loading from either side of the weapon.
