The M3, famously known as the ‘grease gun,’ is a cheap gun used as a temporary gun during World War II. It was named a ‘grease gun’ due to its resemblance to a mechanic’s lubrication tool. The gun has a heavy volt and can fire up to 350-400 rounds per minute. Despite its simplicity and decidedly unsophisticated design, the weapon has been used up to the early 1990s, which has surprised its manufacturers for its longevity.
