The H.C.A.R. (Heavy Counter Assault Rifle) is a modernized version of the World War II BAR 1918 developed by Ohio Ordnance Works, Inc. The weapon is lightweight, with a reduction almost 8 pounds compared to the BAR, and is completely customizable, but still fires the BAR's .30-06 Springfield round (7.62x63mm) and uses the same Browning 3-position gas system. The H.C.A.R. uses a pistol grip, adjustable stock, multiple Picatinny-type accessory rails and can feed from a 30 round detachable magazine, compared to the BAR's 20 round magazine.
