Here's what I think about your right to bear arms. If you want to exercise your second amendment rights you should be issued a musket and a hunk of lead that you could then melt down and pour into a musket ball mold in order to create some nice musket balls for your gun. These you would be able to load and fire out of your musket at a rate of two, possibly three, per minute.
These are the arms your founding fathers used. This is what they had in mind when they said you had a right to bear arms.
If you want something more than what your founding fathers had - you'd better be prepared to have a thorough background check and to give a damn good reason.

ps. wash your hands after making those musket balls - lead's toxic.
