You will likely spend near as much or more replacing the receiver than you would by purchasing another gun.
How old is your son? Under 12 years of age? A .30-'06 delivers quite a kick, and could be uncomfortable to anyone under 120 lbs, or so.
My son is going to be 14 soon. I'm not willing to take this risk with him, though I might try my luck with it at some point if I can't get my money back.
Thanks for taking the time, everyone, I now know what I have.
