Designed in 1932 as a hunting rifle, the Hirschjäger (literally "Deer Hunter") H12 series was produced from 1933 until 1945, with over 350,000 units constructed. The H12 Mk.II (and its variants) saw the most success out of any weapon in the series, with around 120,000 of them being made between 1938 and 1945. In standard "Infanterie (Infantry)" form, the Mk.II had a 5 round magazine, and was operated by a bolt-action system. For reloading, the operator would open the bolt, push the mag release and remove the spent magazine, insert a new one, and close the bolt (using the bolt to reload the rifle after every shot). The Mk.II-A version came equipped with a 15 round magainze in both curved and straight designs. The Mk.II-B was meant as a sniper rifle, and featured a 5-inch longer barrel, and came equipped with a scope (later versions of the Mk.II-B also had a variable-zoom scope). Alas, the reason why the H12 was so successful in its role is because it was used by the German army during WWII, though in small numbers. After the war, Argus Arms Engineering bought the licensing to the weapon, and produced the Argus AIR-H12, which is still used by Lycernian troops to this day.
