The guys there claim to follow all local, state and fed law but yet they don't know the laws. Tried buying a firearm there and they wouldn't sell it to me because I didn't have proof of residency

I have been here a few times to just shop around, use the range and pick up a firearm I ordered online each time the staff is friendly and helpful with any questions I have had I seen some of the negative reviews and never experienced any of those issues or seen them while there especially about the range of you just follow the rules and shoot safe on the range you won’t have a problem I’m looking to purchase a membership as I live close to here
