If there was EVER a automatic gun made that had a more direct method of utilizing barrel gasses I can't imagine what it would beThis thing is about as basic as it gets.
It's hard to realize that this bit of "sideways engineering" came from ol' JMB hisself.
Still, it's so very cool to see and hear.
If what I read was correct, some of his first work in automatic weapons was using a lever action rifle with a paddle in front of the muzzle to be acted upon by the muzzle blast. A couple levers, a spring, and a screw to act on the trigger as the lever closed, and it'd run itself dry.
Full auto Winchester Model 94, anyone?
The 'gun' part of a machine gun is pretty basic. The real difficult bits are the ones that keep it fed with a steady supply of ammo.
