What can I say? I bought an old UK spec .43 X50 marker and 95% of the spares seem to be unavailable in Europe. If you ever owned one of these, you'll know how many seals, valves an... view mored o rings they can chew through.
A simple online order to MCS, with honest worldwide shipping prices, and I've got enough parts to keep this thing fed bits of rubber for at least a year.
