In the 2nd Amendment it says "A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed". The Federal Government is trying to do exactly that, infringe upon our right to keep and bear arms. By saying what guns we can and cannot own it is infringing upon our 2nd Amendment right. It does not matter whether or not it is a "military issue weapon" or not. When our forefathers created this Amendment they had it in mind so that we could  prevent tyranny and if needed overthrow tyranny. That means we have the right to own weapons such as AK47's, AR15's etc. And the fact is that the muskets we used then were the assault rifles of that time. Also an "Assault Rifle" is a fully automatic firearm and of which The Firearm Owners Protection Act of 1986 made it illegal own any made after May 19th 1986.
