The latest M79 project has finally been completed based on the actual M79 grenade launcher of the Vietnam era. The new M79 mkII sports a larger 2″ diameter barrel, an authentic wood m14 rifle stock and a constant air adapter that will support any Co2 source as power(constant air bottles, 12gram quick change adapters or remote lines). The larger barrel will accommodate a larger load of paintballs or launch the new water balloon paint grenades. In addition, the rifle stock has storage in the butt for up to 3 co2 cartridges and the foregrip will store a barrel squeegee or packing ram for the cannon barrel. The mkII also comes with an adjustable rifle sling.
