"...they can eject spent shell casings and chamber the next bullet without human action, but (as opposed to automatic firearms) only one round is fired per pull of the trigger."
Yes, I understand there is a difference between an assault weapon and an assault rifle. It was the very first thing the Wiki article said.....The difference between an assault rifle and a rifle you ask? Assault rifles have a selector switch, they can be used in semi-automatic, burst fire, and some fully automatic but every single assault rifle has select fire capability. Semi-automatic rifles may have similar characteristics such as shortened barrels, pistol grips, folding stocks, and other cosmetic appearances which do not effect the performance of the gun or the efficiency of delivery but somehow they are magically "assault weapons" because some jackass with no credibility says they are. Now, a word to the wise about wikipedia on this topic, that they want to define cosmetic firearms as "assault weapons" is irrelevant, it is an open code source, so basically if enough people actually think that "assault weapon" is proper terminology then of course it will have a page, frankly they do a disservice to the subject by even letting that term survive with any credibility.
"Not to be confused with assault rifle, FGM-172 SRAW, M202 FLASH, or Shoulder-launched Multipurpose Assault Weapon."
