I was at rampart just the other day, during a "cold range" break to check our targets some kids ran up with their AY-KAY with tacticool folding stock, full mag in it, and pointed it downrange with finger on the trigger.

So yes, sometimes having strict range officers isn't a bad thing, depending on the quality of shooter you typically get.

There was some guy with what looked like an NFA uzi, though. That was pretty fun to watch.
