Purchasing through Albany Arms is simple—just four quick steps:
Browse the catalog, apply filters as needed, and open the product page of the gun that best fits your needs and preferences.
Select the quantity and hit “Add to Cart.”
You’ll select FFL during checkout. You may need to ask the dealer to email a signed copy of their FFL to admin@gunly.com, referencing your order number. They must also authorize shipment to their address. This is a general list of FFL dealers and not necessarily a list of who we ship to.
When your firearm arrives, visit the FFL to complete the ATF Form 4473, background check, and any state paperwork. Bring valid photo ID (and permits, if required), pay the dealer’s transfer fee and taxes, then head to the range with your new purchase!
