I am debating how to start my son shooting. He is about to turn five in a few months. I have a big yard but live in a city that prohibits "air rifles." I can easily set it up where I shoot from inside to outside and no one would hear an air rifle. I was also debating a spring airsoft rifle that would fall outside the law in my opinion. Are these airsoft rifles accurate? I would weld up a little plate rack to shoot at that would also act as a pellet stop. Any suggestions? Once he gets comfortable with this then we can go after the 22.
