Long story short:
I want to turn one of my Ruger Airhawks into .22 cal springer.
Before anyone says "sell and buy", I live in NJ and air rifle are treated as firearms. This would involve a FFL and now a NICS check which makes this venture cost prohibited.
A little bit of research tells me the AirHawk is a RWS 34 clone (and maybe their are other branded clones of that).
So, where would be my best bet on finding RWS 34 (or clone) .22 cal barrel?
