Been there, done that, got called a terrorist
Yep, I’ve had hunter call me a terrorist because I own an AK-47, and I’ve had a range (which was run by good ol’ boy hunters) make up new unwritten rules about rapid fire etc., that only applied to me, and blame me for things I did not do. I quit going to that range ASAP.
<rant>Its no wonder those guys can’t comprehend rapid fire, considering the huge sniper rifles they shoot and the fact that most of them only shoot once a year to sight in for hunting season. </rant>
Some people are just assholes, and the only thing you can do is avoid them. It sucks and its not fair, but these days, when a gunowner can get in a lot of trouble based only on an anonymous false accusation, you just can’t be too careful about who you annoy - even when they have absolutely no right to be annoyed. Don’t forget that these assholes are also probably clueless about gun laws, so there’s a fair chance that someday they will be in a jam and need someone to accuse, know what I mean?
Luckily for me there’s lots of ranges around here so I quit that one as soon as they started giving me a hard time, and found one where they’re into practical shooting. Its a lot more fun and educational anyway, because they have tactical rifle classes, hi-power matches etc.
BTW, the rapid fire the good ol’ boys objected to was a 5.56 AK.
Ya gotta love these small caliber carbines especially for rapid fire. One of my coolest shooting experiences ever was at my tactical carbine class at the new range. One night after class we were plinking at steel targets, and I had that AK with a red dot sight. With no recoil, the sights just stay on target - ping ping ping ping… I put a whole mag on the steel as fast as I could pull the trigger, easy as can be. And since it was dark, they all struck sparks off the steel. 
, the battery contacts corrode and its tough to clean the inner one. Also the dot is large and blurry, which is fine for CQB but not for 200 yards or more (we’ve shot out to 400 yards… I admit I missed some at that range!).
