And Nick Murphy if he is doing them anymore.
Or the factory, but will cost you around £250
Shot count should be nearer 60 - 75 shots.Don't think the mk2 can have the mk3 valve fitted;but I could be wrong.Give Dave a ring and have a chat before you send it or drive up there.
Staffordshire custom rifles got my vote.
Had mine done by Dave before Worlds,nice quick job and at a reasonable rate(very reasonable
Shot count about 65-80ish,mine included replacing the original filler valve for a mini Daystate quick fill and a sleeve for the female filler, included in the package was the postage home.
Well pleased and done by someone who appreciates GC2's.
