I went to a show today. While there, I found one of the new Remington AR style rifles, complete with camo finish, scope, light, and laser. I hefted it, found it to feel like a serious rifle. Right next to it on the rack was a carbon fiber AR in desert tan with no optics. Hefting that one felt like about 25% of the weight of the Remington. The thing had an oval handguard and actually didn't look like a real gun. I've held supersoaker squirt guns that were heavier, without the water in them! The price on the carbon fiber gun was $825. If you are going to be doing something that involves carrying an AR for long distances, you might want to look into one of these lightweights. They are unbelievably light.
