Thompson SMG in 30 Carbine
This video explores the rare Thompson SMG chambered in .30 Carbine, a fascinating prototype submitted by Auto-Ordnance for the US military's carbine request in 1940. The video highlights how this modification involved a new magazine, receiver, barrel, and bolt face, while leveraging existing Thompson components. Despite the relatively low cost and ease of modification, the submission was rejected due to exceeding the strict 5-pound weight requirement for the new carbine. The presenter notes that this specific example is serial number 1 and is housed at the Cody Firearms Museum. The description also links to other related prototype firearm videos.
