I've always noticed when reading some old airgun books/magazines you see the workers in the gun factorys dressed in their "arkwright" overall jackets they seem to be checking things properly and they looked like crafts men, now I see more and more being replaced by CNC machines.
Now im not out to upset anyone but as for most of the stuff produced in Turkey and China I personally won't touch it and that's because it just looks rough and cheap (sorry).
Airarms, HW and Daystate for me still produce qaulity rifles however they aren't perfect all the time as we all know and hence we end up spending time and money on tuning.
All I can put it down to is modern working practice which usually means cheap materials, cheap Labour costs, and this is not just the gun industry a lot of goods now a days on the shelves look and feel crap which is what drives up the price of older items from an era where manufacturing took pride in what they made.
