You'll need a roll pin punch set, barrel wrench, torque wrench, upper receiver holder, and they make a block to drop in the mag well to hold the lower. The pin on the bolt catch needs a flat side roll pin punch. Also the front take down pin needs a special tool to install it. You can get away with less but they make life much easier.
