what are the hoops for importing a rifle?

[Grouse]

for what it is worth this is the semi auto only version, ie the swiss civilian version. Never was capable of full auto

[Dave Waits]

Grouse, the problem will be the receiver. If SIG used the same receiver for both the SA civie model and the FA military, it's unimportable. ATFEs' favorite song," Once a Machinegun, always a machinegun." Doesn't really matter if SIG made it Semi-only, if they used the same receiver,the ATFE will state it's easily convertable.

An option would be to see if anybody makes an American receiver in Semi-Auto and buying a 'kit' to build one with.
