The most common Japanese sniper rifle of World War II was the Type 97, essentially a Type 38 Arisaka rifle with a 2.5x telescopic sight mounted to the side of the receiver. About 22,000 of them were made in total (a smaller number of Type 99 sniper rifles were also made). The scope on the Type 97 was zeroed at the factory, and had no external adjustments for windage or elevation. They were chambered for the 6.5x50SR Japanese cartridge, which produced virtually no smoke or flash from the long barrel of the Type or Type 97, making is a difficult rifle to spot (it also had a quite mild report relative to other contemporary weapons). Virtually all of these rifles in the US today have mismatched scopes, which generally means that they will not shoot to point of aim (this one's windage is way off). http://www.forgottenweapons.com
