The US is a participant in ITARS, the International Traffic in Arms Regulations. As such, the US interprets importing gun parts, with the exception of sight parts, in excess of $100 wholesale, as requiring permits to import or export. I don't do any exporting, but I do have a Type 8 FFL for importing firearms. To import an einstecklauf requires the approval of a Form 6 by the ATF. There is some provision for the occasional import by a regular Type 1 licensee. I have purchased inserts from Zimmerman, but the German export fees and shipping exceed 500 Euros per shipment. So what I've done is to have another importer who brings guns in add it to his Form 6, then ship it with guns he was shipping. My cost was to him was $100, I believe, for the shared cost on the insert barrel. I know of gun parts, especially gunstocks being imported making it past Customs, but without a Form 6, if Customs sees it, it will be confiscated.
