How can a 17 year old/teen boy buy a gun?
Depends where you live. If you're British you have to apply for a license, take up a sport like hunting or target shooting and prove you're sensible enough to use a gun. If you're American you can walk into any Wal-Mart, show some photo ID, and go home with a semiautomatic rifle
Unfortunately, you are 17, and the law in the United States says you cannot own a gun until you are 18. May I suggest 3 ways you can own a BB gun? 1) You can wait until you're 18 and buy whichever gun you like. 2) You can ask your parents for a BB gun for Christmas/Present 3) You can ask your mom or dad to buy a BB gun for you, and you can pay them back
