Having recently bought an Airsoft gun (shotgun, 325 FPS. It sucks, i know) and having yet to use it, i thought i'd atleast try the internet for some advice and tips. I've tried talking to some people i know who have Airsoft guns, but they don't really have any intrest in play a beginner like me with a crappy "clearsoft" gun from Canadian Tire. I live in Burlington, ON. I've also talked to people at the S.O.F.P. stores and they've both said that i should probably wait 'ill i'm 18 (alas, that is 5 years too long i don't want to wait) to try and play on a real field. Anything helpful or useful i should know? Some info on starter groups would also be appreciated.
