If you are a member of the range, NO. IMO its called GOOD Karma. At the private range I belong to many of us that are NRA Certified RSO's volunteer our time as RSO's so the members can come and shoot. One of our rules RSO must be present to shoot. I also RSO/SO our Steel, IDPA, ICORE matches. No charge. Its called giving back to the sport and helping support the range and a place to shoot.
This! Its a hobby, not a business oppertunity.
I even paid for my RSO course so I could give something back by having the range open more often as we use a similar system.
