Razor hd lht has very crisp and clear glass, very light weight,locking turret, covered windage, solid reticle with illuminated center dot. Does very well at low light. I have the mil 42mm version on my lightweight 300wsm. Would feel very comfortable shooting at game a long ways out with it.
Another great option is the trijicon credo hx 2.5 15x42. It's Japanese glass, 100moa elevation, very nice sfp moa center dot reticle and is pretty light weight too.
