I would just like to add some balance to the discussion on CZ quality.

I purchased a CZ550 American last year in .308W (as most of you know).
I had the trigger rebuilt to a single stage from the set trigger as that is what I like.
The action was rough to cycle until I used a heavy viscosity lubricant (forget the name) and cycled the action a couple of dozen times.
I worked out a load and took it to Africa and took 7 animals with 7 shots at ranges from 40 metres to 150 metres.

Since then I have had the rifle bedded in anticipation of longer range ( 300-400 yard ) shots at Springbok.

The rifle is fine apart from that.

I will agree, it seems that CZ quality is a bit of a lottery for the members here but there are good ones out there.
