The 505 is clearly a warranty issue.

I would suggest that any rifle to be used on large game such as these two rifles are, will need additional work. This has already been suggested numerous times in regard to CZ's.

The beauty of getting a gunsmith to correct any design or manufacturing problems is that you have control over what is fixed and how. IMHO the CZ's are a great basic platform.

It is dissapointing to purchase a rifle that does not function first up, but these issues are quite easily improved upon and corrected by a competant gunsmith.
