No. You can however have a dealer in another state ship a handgun to a dealer in your state, then purchase the gun through the dealer in your state.
A resident of one state may buy a rifle or shotgun from a licensed dealer in another state IF his home state approves such a purchase (Kentucky will). You may not buy from a private citizen, dealer only, and you cannot buy a handgun in another state.
Yes. "Yes" is only partially correct. In order to buy a handgun in another state other than the state where you reside, you must have the gun shipped to an FFL dealer within your state and pick up the gun there.
Depends on the state's firearms laws.
Gun laws vary from one state to another. You would need to check to see if you are allowed to buy a 22 caliber at 20 years of age.
Strictly speaking, no. You can only buy handgun within your state of residence. However, you can pay for a handgun in another state, have the gun shipped to a dealer in your state, then go to that dealer to pick it up.
Some long guns, although it depends on which state you live in - that's a matter of agreement between states. Handguns, no.
You may sell it to a dealer, have a dealer sell it for you, or you may sell it directly to another resident of Arkansas so long as they are old enough to buy a handgun, and you do not have reason to believe the buyer is not able to legally own a gun. If the gun is being sold to someone in another state, the gun must be sent TO a gun dealer in that state.
In the U.S. you can only buy a handgun within the state where you officially reside. You can have a handgun shipped from another state to the state where you are and pick it up at a gun shop within your home state (this is called a transfer). I doubt Canadian law will allow a local gun shop to ship a handgun to a person in Canada, however, I admittedly know very little about Canadian law.
It's legal to purchase a gun out of state, but the gun is supposed to be shipped to a dealer in your state, and you have to go to THAT dealer to pick it up.
To buy a gun from a dealer in ANY state, you must be 18 for rifles and shotguns, and 21 for any other gun, such as a handgun.
Yes, if you declare it as a firearm. You cannot bring air tanks however.
