I bought a Remington Model 7 when they first came out with them in the late 80's. It has the fiberglass stock and the 18.5" barrel. Weighs a little over 5 pounds. This model is now sold only through the custom shop. I have shot several deer with it and also a couple of ek. One of those elk (cow) was 426 yards, one shot...dead elk. I was using 140gr. Nosler Partition.
I ended up buying my son a Model 7 also when he turned 10 and think it is as close to a perfect rifle you can get for a young person or an adult for that matter.
Presonally though I would stay away from the muzzlebrake. They are very hard on the ears if one doesn't wear hearing protection.
