Most indoor ranges require that you read the rules and sign off on them. They probably all require eye and ear protection. Indoors is very loud. I wear foam ear plugs and ear muffs.
Some require you buy their ammo or lead free ammo so that will determine if you bring your own ammo or not.
Targets, again some may require you buy theirs.
Make sure your gun (if you are bringing one, some rent guns) is unloaded and in a case of some sort.
Enjoy!
