There certainly is not much out there for a six year old. My boy is six and for years i've had a Biathlon trainer synthetic stock rifle which I messed around with for plinking. Technically that's a junior rifle and is pretty tiny. A couple of weeks ago I dug it out and tried it for size on him and it was way too big unfortunately. I'm going to hang on for a few months because the last thing I would want is to cause it to be unsafe due to rushing things.
