Re Norwegianicon seller on Ebay. Just a friendly reminder that the US State Dept has restrictions on imports (into the US) of firearms and components. Barrels, receivers, and pistol cylinders all require import permits. Had a friend try to ship a carbine barrel into the US by Post, and was turned around at the border and returned to sender. I have a dozen carbine USGI take-off barrels that I would like to sell into the US, but no-can-do.
