When you are 18 you can buy a Rifle or Shotgun but what is considered a Rifle Is it a Assault Rifle Hunting Rifle?

Answer 1

A rifle is a rifle is a rifle. As long as it isn't an NFA (National Firearms Act) restricted, or "Class 3" weapon, such as a fully automatic machine gun, or class 2 weapons, which includes short barreled (under 16") rifle, short barreled (under 18") shotgun, a silencer or suppressor, or a destructive device such as a grenade launcher or rifle over .50, or anything which falls into the AOW class such as a rifle disguised as a guitar, there is no legal distinction between types of rifles or shotguns.

If you are buying from a licensed dealer, which would include all gun and sporting goods stores that sell guns, any NFA restricted class 2 or 3 weapons will be clearly marked as such, if not in their own special section. You must be 21 to buy these, plus undergo the NFA licensing process

There is no difference between grandpa's lever action .30-30 and an AK-47 or AR-15 in the eyes of the law, unless of course you live somewhere like California or Chicago or NYC, which all have very restrictive gun laws unique to their jurisdiction.

Basically, as long as you're 18 and live in a free state and can pass an NICS criminal background check, you can buy anything from a single shot .22, to any type of shotgun, to an AK with a 100 round drum magazine, to a belt-fed .50 caliber machine gun as long as it is semi-automatic only.

I hope this answers your question!
