Under federal law, you may be considered a prohibited person if:
- You have had a felony conviction,
- You have been convicted of certain misdemeanors related to domestic violence or are subject to certain domestic violence-related court orders,
- You have been adjudicated a mental defective or declared a danger to yourself or others.
In addition, shotguns, rifles, and their ammunition may only be purchased by people 18 years old and older. Other firearms and ammo (including handguns and their ammo) may only be purchased by people 21 years of age and older.
Please note that both federal laws and the laws of whatever state you’re purchasing the gun in apply, so make sure you also know the applicable state laws.
