Legal Question

i dunno but i put up a post a while back on this and found you could buy one private party @18 if you have the right paperwork. http://thehighroad.org/showthread.php?t=394572&highlight=1858rem

Federal law says you can't buy from a dealer.

Laws in regards to firearms usually apply to transfer in any form, purchase, gift, trade, etc.

You need to check your state laws.

Federal Law...

...prohibits dealer sales of handgun to anyone under the age of 21 but generally restricts possession of an otherwise legally acquired handgun to those over 18. State laws may be stricter (e.g., may require a minimum age of 21 to possess a handgun.)
