One of the best and strongest lever guns ever made. I have a 99 in 308 and won't even think about selling it,,,,,and I have a 77 Ruger in the same caliber, more accurate and a better trigger and I'd let it go if the price were right.
99s will continue to climb. They have many features no other gun, or few other guns, have...like counters for the number of shots left, a smooth top receiver for scopes, side ejection (Marlin, too), the ability to handle 50K plus psi cartridges, and a nice "carry" factor.
I have two stocks...monte carlo for scope, standard for iron sights.
