Shipping, FFL transfer and returns
- FFL transfer: firearms ship only to a licensed (FFL) dealer you choose at checkout, never to a home address. You show ID and complete ATF Form 4473 and the background check at the dealer, who charges their own transfer fee. How FFL shipping works
- Shipping cost: $29.99 flat per order, free on orders over $999. Orders usually leave within 1-3 business days after payment clears and we have your dealer's license.
- Returns: a firearm can be returned before transfer; once transferred it is legally used and cannot be returned for refund, but the maker's warranty still applies. Return policy
- Payment: Secure Checkout. Questions before you order? Contact us or read the FAQ.
