The Remington Company made this film in 1969, showing day to day gunmaking activities of the time.
Pretty neat look at how it was done then, and a large amount of computerization, even in 1969.
P.S. Fair warning, the gal in the Thumbnail is not in the video!
So, crazy thing to come to mind, but as I was thinking about ways that the AR-18/180 and other firearms that used a lot of stamped parts could be brought back into production, I was wondering if some of the smaller stamped steel components could be replaced with 3D printed polymer parts?
