No, never.
No. A person under indictment for a felony may neither carry nor purchase, possess, or have access to firearms - it's treated the same as a convicted felon until they are exhonorated.
A person convicted of ANY class of felony anywhere in the US may not purchase, possess, or be allowed access to firearms ANYWHERE in the US, to include all states, Commonwealths, and unincorporated territories.
If you have been convicted of a felony, Federal law will not permit you to possess ANY firearm. Under some circumstances, a person that has been convicted of a felony under STATE laws may have their firearms rights restored. You need to consult an attorney. Unless that has been done, possession of a firearm by a felon is a serious Federal crime.
In most jurisdictions, if a person has been convicted of a felony, they can never own a firearm again.
With enough money, lawyers and time, it might happen.
Not sure what you mean by "class you" but any felony precludes a person from owning a firearm and no state will issue a firearms permit to somone who is a felon, unless you have had your rights restored.
If you have convicted of a felony, or are under indictment for one, Federal law does not permit you possess any firearm. Title 18, US Code, section 922.
No.
You need to consult a lawyer familiar with firearms law.
It does not say that in the Constitution. Felony firearm rights are a matter of Federal Law and state laws that say a person convicted of a felony shall not possess, use, transport, sell, purchase, carry, ship, receive, or distribute firearms.
To get a correct answer you should find a lawyer who specializes in firearms law.
In the United States, the law is called the felon-in-possession law (18 U.S.C. § 922(g)). In general, convicted felons are never allowed to own or possess firearms of any type. In rare cases, the courts may reinstate a convicted felon's right to firearm ownership.
