Im not exactly an expert on firerams, but does a fully auto make a weapon a machine gun? I thought they were just automatic rifles.
I thought machine guns were guns like the m60 and mag-58
There's differing ways to define a 'machine gun' in gun terminology, none really official, or particularly consistant. Generally, pistol caliber full auto's are referred to as sub machine guns, rifle caliber dedicated full auto's as machine guns (sometimes light machine guns), select fire (full or semi auto from the same gun) rifle caliber as 'assault rifles', larger than rifle caliber but smaller than cannon are sometimes called heavy machine guns, and at some point (I'm not sure what caliber designation, definitely by 20mm) they become automatic cannon. Legally, anything that fires more than one shot with a single pull of the trigger is a 'machine gun'.
