Easy answer is no. I bought an SSG10 plus extras for over £500 with no import fee’s. I checked this with novritsch and they ship with a UPS option that covers everything. Only thing you might need to complete is a firearms declaration, if it’s been sat in customs for a while I would recommend you call UPS and they’ll usually send it out once you give them a nudge. I’ve had to do it 3 times and had no issues once I rang them.
