10-Round internal box magazine loaded via two 5-round stripper clips
The Type 4 Rifle, often referred to as the Type 5 Rifle, (Japanese: 四式自動小銃 Yon-shiki jidousyoujyuu) was a Japanese experimental semi-automatic rifle. It was a copy of the AmericanM1 Garand but with an integral 10-round magazine and chambered for the Japanese 7.7×58mm Arisaka cartridge. Where the Garand used an en-bloc clip, the Type 4's integral magazine was charged with two 5-round stripper clips and the rifle also used Japanese style tangent sights. The Type 4 had been developed alongside several other experimental semi-automatic rifles. However, none of the rifles entered into service before the end of World War II, with only 250 being made and many others were never assembled. There were several problems with jamming and feed systems, which also delayed its testing.
