Final answer:
Federal law prohibits convicted felons from possessing firearms or ammunition, regardless of how they are obtained. This is influenced by the Second Amendment, as interpreted in landmark cases such as District of Columbia v. Heller, which acknowledges individual gun rights but allows for certain restrictions.
Step-by-step explanation:
The question pertains to whether a convicted felon has the right to possess ammunition, even if it is not purchased. Under federal law, it is illegal for a felon to possess firearms or ammunition, regardless of how they are acquired. This includes both possessing and receiving ammunition. The relevant law is derived from various judicial interpretations of the Second Amendment, as well as specific federal statutes such as the Gun Control Act of 1968.
Particularly relevant is the Supreme Court decision in District of Columbia v. Heller (2008), which held that the Second Amendment protects an individual's right to possess a firearm for traditionally lawful purposes such as self-defense within the home. However, the Gun Control Act still restricts this right for certain individuals, including convicted felons, who are prohibited from possessing firearms and ammunition.
