US WWII M3 Grease Gun Non-Firing Replica

The M3 Submachine Gun was adopted by the US Army on December 12th, 1942, as a cheaper alternative to the Thompson (the "Tommy Gun"). Designed by General Motors' Inland division to use parts that were mostly stamped instead of milled, production issues and specification changes delayed front-line service until mid-1944. Chambered for the same .45 ACP rounds as the Thompson. Nicknames "Grease Gun" and "Greaser" caught on because it looked so much like the mechanic's tool. Telescoping stock like the original. Removable magazine and some moving parts. Metal construction.
