You put Zastava in the second tier and that's somewhat unjustified.
They make superb Mauser style bolt action rifles and have done so since 1924. They also use their own in-house barrels and they are superbly made and capable of excellent sub MOA accuracy.
The problem is that from time to time importers like CAI sell them with rather crude stocks - although the metalwork is still very well done, with a very nice polish and a wonderful deep blue finish.
Zastava made the Zastava Model 70 for Interarms for nearly 30 years, who sold them as the Interarms Mk X. Interarms also sold the Zastava Model 85 as the Mini Mk X for about 15 years. They were available in both complete rifle format and as barreled actions, often used to create some very nice custom rifles.
Charles Daly sold the Model 70 and Model 85 with composite stocks and Remington sold them as the Rem 798 and Rem 799 with laminated wood stocks. Which of course mean that between the Mk X, Mini Mk X, 798, 799 and Charles Daly models out there, you can readily find an after market or NOS stock to replace what is on the current CAI imports, and end up with a nice rifle with decent wood, for a lot less than you could buying something comparable.
The same applies to the CZ 99 Precision - a .22 LR bolt action repeater that has been imported by Remington as the Model 5, as well as by Charles Daly and currently by CAI. They are also well made rifles with very heavy, stiff receivers that are capable of excellent accuracy.

You've also painted everything made by Chiappa with the same broad brush.
Chiappa does market some seriously low end firearms. However, Armi-Sport (which produces the actual firearms as a subsidiary of Chiappa) makes some excellent reproductions of various rifles like the 1859, 1863, and 1874 Sharps, as well as a few different variants of the Winchester 1892, all of which are very nicely made. You'll find them sold by Cimarron and other vendors who order them with very high specifications for finish and function.
