Stay the ground, educate as many as you can about what a "assault" rifle consists of.
+1 A long long time ago one of the original Evil Anti-Gun Legislators originated the assault rifle.
"In July 1944 at a meeting of the various army heads about the Eastern Front, when Hitler asked what they needed, a general blurted out "More of these new rifles!" This caused some confusion, but once Hitler was given a chance to test fire the MP44, he was impressed and gave it the title Sturmgewehr. Seeing the possibility of a propaganda gain, the rifle was again renamed as the StG44, to highlight the new class of weapon it represented, translated "assault rifle, model 1944", thereby introducing the term."
That is an entry on wikipedia, my "military small arms of the 20th century" also links Hitler to dubbing it assault rifle.
This story had been refuted on some sites partially in that Sturmgewehr translates into Storm rifle (as to Storm a bunker.), not assault rifle, but also that it was a poor allied translation that made it assault rifle.
In either case the one true assault rifle is the StG44 Sturmgewehr, all the rest are its offspring automatic rifles in an assault role.
