You must provide a valid PAL or FAC, FFL before you can take property of any won items.

All items must be paid for within 24 hours of the auction completion.

American and International Buyers:

Not all items can be shipped into America. Please ensure you follow the regulations laid out by BATF before bidding. Canada Post and many other shippers will not transport guns. It is up to you to arrange for shipments into your state or country.

Be advised that many items related to firearms may also have regulations including gas masks, body armor, etc.

Americans can review BATF for regulatory information.
