This is a premium scope that will serve you well in any lighting condition...from dawn to dusk. The red/green mil-dot reticle will work for most bright-light conditions, but the 36-color option will give you the edge in dimmer light. The biggest advantage to the additional color is when you're shooting something that's the same color as your reticle! If you're hunting and your quarry is hidden among greenery, use a contrasting color to see all the points on your lit mil-dot reticle. The 30mm tube lets in a lot of light, and the emerald-coated lenses offer the most amount of light compared to other types of coatings. The True Strength platform can take the harsh 2-way recoil of magnum spring-piston air rifles, but this scope is also suitable for firearms and airsoft guns.
