So I just bought an Xmag, but it hasn't been shot in at least 5 years. What items such as o-rings do I need to freshen the marker up and where can I buy them? Also, I need a power cord for the charger but it's probably easier to just buy a new one. Where can I get one and whats the model number? I'm in Japan so I cant just swing by radio shack... I'll have to order It. Much appreciated for the help guys!
