In the Euro market it's all bolt actions, and in some venues illegal to even take a follow-up shot. So a heavy high magnification unit that looks like a classic rifle scope for that slow and sure first shot matters a lot. In the US, being compact and fitting on a fast follow-up AR15 matters more.

I am not sure that the logic follows. Pulsars don't have high magnification. Thermions aren't particularly heavy, either. The looks of the "classic rifle scope" are simply for use with scope rings, which is more popular with the European market, in large part due to the use of bolt actions.
