How old do you have to be to shoot in the range? I was thinking of bringing my son and his friend

We are the guns shop not the range. You want Lakewood Shooting Range. www.lakewoodshootingrange.com

I took my 13yr old son today and was told that you have to 18 or older to use the range

I think so why not my son did he was 12 yrs old

This is from their website: Customers must be 18 and older to enter the range and to rent long guns. Customers must be 21 and older to rent handguns.  No spectators! No exceptions.

I think 12 but you should call to confirm before bringing them
