I'm in Virginia and belong to a members only range. When checking in and you bring your suppressor you must get the serial number verified by the guy behind the counter(range representative). It's to make sure you own it legally and keep BS problems away from the club. I'm OK with that. All members are told to act and speak up when they witness "safety" related issues. Mention it to the person and then take it to the office. I'm OK with that too. Pretty laid-back club overall. Never had a member ask me anything about my suppressor except what brand it was..
That sounds like some commies run your range.
What the hell is wrong with people? You let them keep a copy of your stamp?
Then again I'll never understand going to a range with staff. We're all able to be safe all by ourselves 99% of the time, but we do have RO's for organized matches.
