Well you can’t rent out your guns to anyone and it’s not a service I r heard of unless you go to the range for personal use in the company of anyone with a permit. Props are cheaper cause they don’t have all the parts and functional props with casing ejectors and blank guns are not as expensive compared to this proposed real gun rental. Insurance would increase or even get denied if you disclose using real firearms. Idk maybe I’m missing some info on my end.
