A touch & go affair: sometimes we have had various CZ-UB project managers, a CZ-USA marketing director, etc. BUT never continuously, so your best bet is getting in contact with CZ-USA(if rifle bought in U.S.) and ask for the gunsmith for technical problem or questions. On the other hand if thinking more about a business proposal or suggestion give the Marketing Director a call.
Let us not forget that the Shotshow will leave these ref. key-people busy like hell, idealy contact them in 2 weeks.
If a technical problem: spill your problem to us we're there to help each other.
