Thanks very much for the detailed pictures Bartok, these will absolutely be the best on the web so far and are invaluable.
Apologies if I came across as prickly...I truly am intrigued by the new 600's and I do wish them to succeed and if sales are good maybe the aftermarket stock manufacturers can come up with something that instills more confidence as to solid stock and action mating.
It's all good! The CZ 600 will sink or swim on its various merits or failure points, regardless of our opinions. I just want mine to be in .300 Bk and then I will be a happy camper. Hopefully it is technically do-able while being financially achievable/sensible. Time wlll tell. I will start sending out emails tomorrow to some of the bigger names in the firearms machining business. Dlask, Herron Arms, RDSC, Tactical Ordnance, etc, etc. I will have to narrow it down to one proposal, as I have only the one Barrel to send off for duplication (or removal and re-use) of the Lugged Barrel Extension. Then it is just a matter of time and money to get what I want...
