I just don't see how crazy folks being able to legally bear damn-near military grade weapons is necessary to the security of a free state. Folks need to admit to themselves that we are not living in a time when the security of this country is dependent on an armed civilian population. Self protection is the only reason I own guns because as long as we have the National Guard and the most powerful military in the history of the world, the security of the free state is not threatened. Now, if you are talking about taking up arms against the USA, you will need more than an AR for the reasons stated in the previous sentence.
