Bang for your buck – literally. The grenadier variant of the M16A1 was also introduced during the Vietnam War, where the concept of a UGL (underbarrel grenade launcher) first came into common service amongst the American troops. This retro masterpiece from E&C bares a gunmetal body, full markings, a working UGL with flip-up/down sights and comes with the classic 20-round style of mag. Tap-tap!
