Eberlestock X1 is perfect for what you're looking for. The rifle scabbard is awesome, the pack weight is light, it can still haul smaller loads just in case, and the price is good. I love mine. I know there are others that carry a rifle, but who wants to have to strap it in and unstrap it all the time? You just slide it in on the X1. You take your pack off and you don't have to worry about the rifle flopping around and the scabbard protects it. I can't say enough about mine, I love it. Here's mine.
