KNOW YOUR RIFLE During the Korean War, approximately 126,500 short and 6,650 long Type 99 Rifles were re-chambered under American supervision at the Tokyo arsenal to fire the U.S. Military M2 -.30-06 Springfield cartridge. These modified rifles were fitted with an elongated magazine well and featured a notch cut in the top of the receiver ring in order to accommodate the .30-06 round's 1/3 of an inch greater overall length. This then is a Training Manual for the converted rifles and addresses inspection of the weapon, care, assembly and function. As expected this instructional book names all of the Arisaka rifle parts and details what they do. Its illustrations show those parts in mechanical drawings. Naturally there is a section on disassembly and assembly of the Arisaka Type 99. The bayonet is covered briefly, as are the different types of .30-06 ammunition that can be fired out of the rifle ie M-2 Ball, Tracer, Armor Piercing, blank. The section on the anti-aircraft sights explains how the sights are to be used and which marks on the sight arms correspond to speed and distance. In other words, the narrative explains how to use the sights to shoot at aircraft. (Golden BB notwithstanding, good luck with that ) Even if your Arisaka is not a .30-06 conversion, the contents of this book make interesting reading and for the most part are applicable to the Imperial Japanese Arisaka rifles.
