Re: Any new C&R guns coming available?
C&R items are becoming available all the time, under the 50-year rule. But if you mean vast quantities of military surplus, I think most of that has dried up. Modern wars are fought with automatic weapons and, barring an unlikely change in US law, those will not be importable even if they came on the world arms market.
There might be warehouses full of K.98k's someplace, or more Mosin-Nagants sitting around, but those have been pretty well found and picked over already.
