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. Shipping method is at BT Gun Company’s discretion; ammunition and oversized accessories are charged at actual shipping cost. We do not ship to Hawaii or Alaska.
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.
