dismissive...check out this excerpt..
"Gun-makers call the civilian AR-15 a “modern sporting rifle,” and insist that the restriction on automatic fire somehow neuters the weapon. The industry’s trade group, the National Shooting Sports Foundation (NSSF), maintains that “AR-15-style rifles are NOT ‘assault weapons,'” adding that the guns “look like military rifles . . . but function like other semi-automatic civilian sporting firearms.” This line of argument is hard to square with the Army’s own Field Manual, which instructs soldiers that semi-automatic fire is the “most important firing technique during fast-moving, modern combat,” adding, “It is surprising how devastatingly accurate rapid semi-automatic fire can be.”
btw, as a 16 yr old I was given responsibility for running the rifle range at our scouting district's summer camp...while the guns weren't AR-15s, I certainly understood the difference between .22 Long Rifle rimfire and centerfire ammunition...and I've fired that centerfire type in both low and high velocity weapons...must say, though, I'm not up to date on teh latest squirt guns.
