– “Agree. Now I know that ‘assault rifle’ is an emotional term, yet I still hear it used even by some gun owners ?!” That’s because the author’s claim that… ““Assault Rifle” is not a clearly defined term and is more of a marketing or political label.” …is patently false. He seems to be confusing the term “assault rifle” with “assault weapon”, with the latter being the actual ill-defined “marketing or political label”. The term “assault rifle” is actually fairly well-defined, and is based on the distinguishing characteristics of the rifle that gave us that term….the WWII German “Sturmgewehr 44” (literally translated into English as “Storm Rifle”, with “Storm” being used in the sense of “storming”…or assaulting….an enemy position, hence “assault rifle”). The characteristics of an assault rifle are: – Has fire-control selectability between semi-auto and full-auto/burst modes.– Uses an intermediate-power cartridge.– Uses a detachable box magazine as the ammunition-feeding source.– Has an effective range of >= 300 meters. So, no…not an undefined term at all. The absence of the first characteristic (select-fire capability) is why AR-15s and other civilian-legal rifles are not “assault rifles”, and why gun-control advocates apply the meaningless term “assault weapon” to it.
