Be the first to review this product

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 BDC reticle, meanwhile, is perhaps the most compelling feature, as its trajectory-compensating system is designed and calibrated to provide fast, simple aiming points for various shot distances. The unique system integrates a series of small "ballistic circles" to produce an unobstructed view of the target.

In addition, the riflescope is prepared for years of reliable service thanks to its 100-percent waterproof, fogproof, and shockproof housing. The scope is O-ring sealed, oxygen purged, and nitrogen filled to prevent fogging, while the waterproof performance is guaranteed, even with the windage and elevation caps off. Other details include a quick focus eyepiece; a locking side-focus parallax adjustment; interchangeable turret technology with target-style windage and elevation adjustment knobs and caps; enhanced ring spacing that allows you to mount the scope on virtually any rifle; and a unique zoom control with rearward facing numbers.
