Shipping & FFL

Firearms are shipped only to a Federal Firearms Licensee. We must have a signed copy of the receiving dealer's license on file before shipment. Once the firearm arrives, you complete ATF Form 4473 and a NICS background check with that dealer. Transfer fees are set by, and paid to, the receiving dealer.
