"The European gun makers are going to the switchable barrels big time."
If I understand correctly, this is due to restrictions in Europe regarding multiple gun ownership, making owning multiples quite expensive. Switchable barrels are a countermeasure there, but it also is expensive (albeit not as much so as purchasing a new rifle and paying the fees for it). Furthermore, I understand the new barrels are only made by the original manufacturer, which makes the owner totally dependent on the manufacturer. (I think I read this in a gun mag review of a Blaser rifle--not sure).
I think our current firearms culture (especially many of us on this forum) prides multiple gun ownership too much for switchable barrels to make significant inroads into US markets. I could be wrong, though...and of course wish T/C all the best. Doubt I'll be purchasing one, though.
