Just looking at parts and differences for semi-auto and full auto... Looks
like a full auto just lets the hammer go, the bolt cycles the hammer, when
you let off the trigger, the hammer is caught. For semi-auto, it looks like
the trigger releases the hammer, when the trigger is held, the disconnector
catches the hammer, when the trigger is released, the trigger blocks the
hammer and the disconnector releases. So it looks to me like a semi-auto
would fire full auto if you left the disconnector out, is that correct?

I'm not thinking about making a machine gun but couldn't help noticing it
looks like extra effort to turn an auto into a semi-auto. I wonder, if the
so called "assault rifles" are banned, people that have them undocumented
might as well make them full auto since they would be illegal anyway. I
don't have illegal guns, I have "Undocumented" guns.
