Side-opening barrel accepts all low velocity 40 mm natures including less-than-lethal and non-lethal natures.
Cold hammer forged, plasma nitride treated steel barrel allows continuous high rates of fire without fear of barrel wear.
Two-position ambidextrous safety levers block trigger and firing pin movement while an integrated 'off-bar' safety prevents accidental discharge while seperated from the rifle.
Co-located triggers enable reactive and accurate fire from the grenade launcher without having to change grip.
A single detended sliding pin retains the grenade launcher on the F90 lower rail allowing the launcher to mount and dismount in seconds without tools or parts or specialist training.
