Carbines have been around a long time, as the shorter more agile counterparts of thier larger
cousins. But it wasnt until Mauser produced the broom handle a semi auto pistol with a detachable
shoulder stock did they take on a whole new meaning. There were a lot of guns made on this concept.
But as far as a true mass production gun with reliability the C96 broom handle took the spotlight.
And for a long time also, then America produced the short stroke piston SA rifle invented by a jailed
convict. And eventually this lead to the M1 carbine, which was no match for the STG 44.
Metal stampings like a modern H&K ,and mass production of a true assault rifle was without a doubt
the wave of the future. A Spanish company built what was called a CETME, the precursor to the
H&K G3. But it was still a main battle rifle. Cartridge size made the modern day assault rifle what it
is today. As theaters of war changed to assault tactics so did the weapon of choise for a modern army.
For now anyway, that could change if two super powers ever butt heads again. By the way I learned
all this by watching the history channel !
