Well Ive only played paintball once, but used to be pretty into airsoft (dont know if you call it the same on the other side of the pond, but its BB guns). Had a nice metal Beretta with silencer and a couple of mags for £140.

Anyway, if you want to get him out the house a little, how about taking him out on a hunting/camping weekend? Gun laws are more relaxed in the US than the UK. Plus, it allows you to spend some father-son time with him :thumbsup:
