Ohio Ordnance Works is an American firearms company which, perhaps most notably, manufactures semi-automatic versions of the Browning Automatic Rifle M1918. Though they produce clones of the historical versions of the rifle, they've also modernized the design in the form of the HCAR. Standing for Heavy Counter Assault Rifle, the HCAR is a modern semi-automatic battle rifle in .30-06 Springfield and fed from a new 30rd magazine.
