Troy Industries is best known for the rifle that replaced what model in the US Army by 1961?
M14 rifle The M14 rifle, officially the United States Rifle, 7.62 mm, M14, is an American selective fire automatic rifle that fires 7.62×51mm NATO (.308 in) ammunition. It gradually replaced the M1 Garand rifle in U.S. Army service by 1961 and in U.S. Marine Corps service by 1965. It was the standard issue infantry rifle for U.S. military personnel in the contiguous United States, Europe, and South Korea from 1959 until the M16 rifle began replacing it in 1964. The M14 was used for U.S. Army, Navy and Marine Corps basic and advanced individual training (AIT) from the mid-1960s to the early 1970s.
Arisaka The Arisaka rifle (有坂銃 "Arisaka-jū") is a family of Japanese military bolt-action service rifles, in production and use since approximately 1897, when it replaced the Murata rifle (村田銃 "Murata-jū") family, until the end of World War II in 1945. The most common specimens include the Type 38 chambered for the 6.5×50mmSR Type 38 cartridge, and the Type 99 chambered for the 7.7×58mm Type 99 cartridge, which was comparably powerful to a modern .308 round. Many thousands of Type 99s and other Arisaka variants were brought to the United States by soldiers as war trophies during and after World War II.
