A must-have for big-game hunters, the Nikon Monarch 3-12x42SF riflescope sets the standard for scope performance. The riflescope offers such features as a one-piece, 1-inch main body tube; a creative Eyebox design with a huge ocular that provides a 4x magnification range and 4 inches of constant eye relief without sacrificing the field of view; an ultra ClearCoat system for 95 percent light transmission; and fully multicoated, super-high-performance lenses.

After the lenses are cut and polished, Nikon coats them with multiple layers of anti-reflective compounds. The compounds serve to boost light transmission, improve contrast (to pull game out of its surroundings), deliver true color rendition and flare-free viewing, and enhance the overall image quality. The scope's Nikoplex reticle, meanwhile, is a favorite of American sportsmen, with thicker posts on the top, bottom, and sides and thinner center crosshairs for precision aiming under all light conditions.
