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 American M1 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.
