M6 “Drill Gun”

In 1941 the American war machine quickly understood that their Thompson submachine gun was far too expensive and took too long to manufacture due toe small and complicated parts. The answer to this problem was of course the M3, commonly known as the Grease Gun, thanks to its looks.
I have always been intrigued by this gun. There’s just something about it. And actually, there really was. It’s got some really clever design elements to it. If you haven’t already, watch @forgottenweapons his video of it. The gun consists of two molded sides welded together along the middle, with some bits and pieces welded or screwed into it. It also supposedly runs like a charm, being both reliable and very controllable due to its low rate of fire.
A while back I made a tiny doodle that was inspired by the manufacturing process of the M3. Since my usual style of firearms design is sleek and semi-futuristic, making a World War Two gun wasn’t exactly in my comfort zone. I felt up for the challenge.
Steel tubes, stamped steel magazine, two molded pieces of receiver welded together. Parts that made sense and served a function. And after the base design was complete, a used-and-abused painted suppressed version just had to happen. 
I present to you: The M6 “Drill Gun”.
