No ... but their may be an age requirement.
In most states, you just have to be 18 years old.
In the US, State law generally requires you be 18 to BUY a pellet gun. It is up to your parents to decide if you can have one, and you are under 18.

I think you mean pellet gun. That is a gun that fires a small lead pellet but does not use gun powder. It uses compressed air or compressed gasses to push the pellet.
A pellet gun is not adequate for protection, and will get you arrested.
Any pellet gun should be handled like a real firearm. Yes you can be killed with a pellet gun under the right circumstances.
It all depends on the model and who made the pellet gun. I suggest that you re-post the queston with the model and make of the pellet gun to get an answer.
I don't believe such a thing is for retail sale
