I have to send a rifle to NY for some warranty work. The rifle is a cash and carry .22LR lever. How do I legally send it? Do I need to send it from an FFL, or can I use USPS since its 'unregulated?' Do I have to remave the magazine tube or anything(I think the company wants it whole). Should I use a plastic rifle case, or put it in a cardboard rifle box and add some bubble wrap? Not really sure how to go about this, but it is getting a new barrel so it is worth the hassel. Thanks
