well now you need an AR wrench to get the existing nut off and an upper vice block too. and a torque wrench and grease to get new nut on.....
I picked up an ATI free float kit on my way up to work, it comes with its own barrel nut that the hand guard screws onto.
I promise I wont bug you guys until I get back next week. This was something I was hoping I could do sitting in my room in the evening but its not looking like it anymore.
