Nikon Gold models are heavier then other scopes but it all depends what type of hunting this scope is going to be used for. If this scope was to be used for sitting in a tree stand then the weight wouldn't be a factor, but using this scope for trailing through the bush then it would be definitely be a disadvantage. This scope might also be a plus on a rifle with a heavy recoil. It all depends on the individual. The 30mm main tube, well that’s another thing. It all depend on individual again.
