Steve, yes Sir, by Federal Law, you can purchase Long Guns (Rifles/Shotguns) across State lines if you qualify and the firearm is legal in both States. You can use the Sevierville Store as your FFL if they don't have the AR you seek in stock there. You can look at the AR listing in the lower right to check if it is in stock at the Sevierville Store. If not, just use it as your transfer FFL when ordering from Buds.
