It'd be simpler to kick a hornets next and hope not to get stung, than to try to get a straight answer to that question.
First you're going to have to determine which set of "rights" you're talking about?
http://en.wikipedia.org/wiki/Natural_and_legal_rights
I've never read anywhere, where the government has the "right" to limit your "right" to self defense.
We all have a "right" to attempt to survive, protect ourselves, our loved ones, and to a lesser degree, our property. You know, the whole, life, liberty and the pursuit of happiness thing...
That said, we
don't have a "
right" to do it with a firearm.
The constitution (depending on which justice is proffering thier opinion today) does grant us the "right" however (by government) to "keep and bear arms.
But it doesn't say squat about concealing them.
Several states antiquated and prohibitive gun laws have been overturned in recent years as a result of these constitutional arguement.
So based on that very limited dissertation, I'd have to say yes, you have a "right" to protect yourself, and if you meet the criteria, you have a "right" to keep and bear arms.
But the State has the right to control "how" you bear them to a degree.
Just my $.02
