I've had/have quite a few "light" rifles. Some others on the less expensive side to consider besides what has been mentioned.
Ruger Ultralight
Remington M7
I've had the above mentioned, a couple actually, as well as 700 Mountain Rifles, a Kimber Montana, and a couple Winchester Featherweights, as well as a smattering of "sporter weight" rifles. M700's are probably the lightest of the sproters, and really with a stock swap and a light scope/ring setup you can keep them under 8lbs on a short and just over on a long.
They all have a bit different feel to me, they all were more than accurate enough for my level of shooting/hunting, and others shoot way better than I can shoot them in the field.
I'm pretty partial to the Mountain Rifles, I agree with T-Bone, they take a wander after about 3 shots, before that... the two I have are the most accurate rifles I own, of about a dozen currently.
I've been using a Kimber Montana for the last couple years, it shoots well on the bench, but I'm on the fence with how much I like it when hunting/shooting. Its really hard to shoot off-hand, and I have to be really diligent about trigger break to make sure the movement doesn't pull it target. The trigger is pretty light already. That's 100% my fault for not shooting it enough, though. Its a dream to carry though. Right at 6lbs scoped and loaded.
I really don't see any advantage to the Mountain Accent or Adirondack. The weight savings is minimal, and if you are really hung up on the couple oz, you can swap the Montana trigger guard for and aluminum one and swap out the bolt for a Ti version and get half way to the weight difference for about $150...
Good luck with shopping.
