Out of the box - They're all flawed in one way or another.
It's only the problems / types of problems / weaknesses that differ.
Tony's Slavia 634 is probably the most under-appreciated rifle I can think of. Its totally great, and all he needed to do was tweak the main spring in the trigger (I think).
I've just bought one.
Looking at the numbers (bore & stroke, TP), you could easily ignore it for UK sub-12 use. But it seems well finished, and hopefully worth some time and money applied to it.
Biggest flaw so far is in the stock design. Looks nice, but apart from a low comb, the reach from pistol grip to trigger is rediculously long. Even with a set-back blade, it'll be long. Which is a real limiting factor to me. Unless perhaps the action can be Frankenstien'd into a different stock... Hmmm...
