Hi everyone my friend has the Umarex Smith & wesson revolver and I am trying to help him track down the broken part. It is the piercer for the co2 bulb (which I guess is puncture body complete unit, PW251 Chambers list at £14). it has a lump out of it. Chambers and Silco show an exploded diagram but I can't upload it here for some reason.

Has anyone experience stripping these down please, or know how much to expect a gunshop to charge?

Many thanks

Andy
