No. You are forbidden to legally posess a firearm and your record always follows you.
A felon cannot purchase or possess a firearm of any type. This goes for every state
Felon = Federally prohibited from possessing a firearm. It is considered illegal in every state for a convicted felon to be in possession of a firearm. By definition, a firearm is a weapon that is designed to expel a projectile by the action of smokeless or black powder. A felony firearm charge can also be brought against convicted felon who is found in possession of a firearm, regardless of the intended or actual use of the weapon. The offense level for this type of felony firearm crime also varies by state but is greater when the gun is loaded, kept or used unlawfully. The laws governing the penalties for felony firearm crimes vary by state and the specific circumstances of the crime. A person can also be charged in a felony firearm case when they knowingly purchase a firearm for a felon, an offense called "straw" purchasing. It is also a felony firearm crime to purchase, or otherwise handle, a firearm with the intent of furnishing it to a convicted felon.

Not with a firearm.
Not a lawyer, but I am going with YES on this one. A convicted felon attempting to purchase a firearm is attempting to commit another felony. Police officers- on or off duty, may generally detain a person that commits a felony in their presence.
Under federal law, no felon may purchase, possess, or be permitted access to firearms. It doesn't vary between states. If the felony in question is defined as a felony only by state law, and is not a felony under federal law, then it may be possible to apply for relief of disability.
Purchase one from a licensed dealer, purchase one from another resident of Missouri, or be given one as a gift by another Missouri resident.
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.
Not in Colorado, nor in any other state or territory of the US.
Yes, if the conviction was for felony DUI. In a few states, you must have a state permit to purchase, and some states may withold that permit for a recent DUI. However, we do not know what state you are in.
