Shipping and Delivery

PROCESSING & SHIPPING

Orders typically ship within 1–3 business days (Monday–Friday) after payment and all required documentation are received. Time to arrival after shipment depends on the carrier.

FIREARM TRANSFERS

  • Firearms must ship to a licensed FFL dealer of your choosing — confirm with them first that they can accept the transfer.
  • Your receiving FFL will need to email their license to [email protected] before we can ship.
  • Inspect your firearm at your FFL’s location before signing ATF Form 4473 — once signed, the firearm is considered accepted.

You’re responsible for knowing the firearms laws in your state before ordering. For complete shipping, returns, and restocking-fee policy details, see our Shipping & Returns page.
