Stop calling them ASSAULT WEAPONS!!!!!!! They are either military surplus rifles, or semi-auto rifles which LOOK like military rifles, but aren't.
The functional difference between a military assault weapon and the civilian knock-offs is that most assault weapons like the M16 & Kalashnikov have a select fire switch that allows the soldier to switch from semi-auto (1 shot per trigger pull), 3-shot burst (1 trigger pull generates 3 shots at the firearms design cyclic rate) and full auto (will fire as long as trigger is depressed).
The civilian models are capable of semi-auto fire mode only.
Some Americans mistakenly feel that you can appease or placate the gun grabbers by giving up 1 kind of "bad" gun and then they will go away.
The antis will transfer the "bad gun" donkeys tail to every type of gun until there is not a single firearm left in civilian possession.
YOU CANNOT APPEASE THE GUN GRABBERS - THEY WILL EVENTUALLY TAKE AWAY ALL CIVILIAN FIREARMS IF WE LET THEM !!
