18 for long guns, 21 for handguns and NFA regulated items. That's federal law, and applies to every state and territory of the United States.
18.
You have to be 18 to buy a long gun and 21 to buy a hand gun.
A good start is to visit a gun dealer. You will need to have proof that you reside in Louisiana, are at least 21 yrs old, and will need 2 forms of ID. The dealer will have you complete a Form 4473 that asks you about things that would prevent you from being able to buy a gun, and conduct a background check with the FBI.
Louisiana doesn't have gun registration to begin with.
In the US, 21 years old.
You problably can, just make sure you have a permit and are legal of age.
