All the power needed for long range varmints, yet a big enough field of view at the low end for close-quarter hunting makes the NIKON Monarch 4-16x42 SF Riflescope, Nikoplex Reticle, Matte Black (8421) an ideal choice for the all-around hunter.
Nikon designed the Monarch around a new optical system created to give shooters increased versatility and superlative performance with virtually any type of rifle, in any caliber and in any imaginable hunting situation.
While still maintaining the American-preferred one-inch diameter main body tube, Nikon engineers developed the new Monarch series to not only provide the shooter with a big, bright, sharp sight picture, but at the same time minimize the overall length of the riflescope - and maximize the mount ring spacing capability.
The resulting line of riflescopes pushes the envelope of optical performance with Nikon's lead-and-arsenic-free Eco-Glass lenses and trademark Ultra ClearCoat anti-reflective multicoatings, is fast-handling, pleasing to the eye and very importantly, allows for mounting on virtually any rifle - even magnum-length actions.
The Monarch riflescope features the Ultra ClearCoat optical system, which provides the shooter with a bright, sharp, incredibly flat sight picture and light transmission up to its theoretical maximum - 95%.
In addition to the enhanced ring spacing, the new Monarch riflescope design includes the new Monarch Eye Box design with its impressive 4-time zoom range and a very comfortable four inches of eye relief that remains constant throughout the power range without sacrificing field of view. In contrast, most competitive riflescopes supply less than 3-times magnification zoom capability and eye relief that varies by as much as a full inch between high and low powers.
The Monarch's massive ocular lens also delivers both a large high-resolution sight picture and the maximum field of view corresponding to each power setting. As an additional convenience feature, Nikon has placed rear-facing magnification indicators on the zoom control and included a quick-focus eyepiece on the new Monarch Eye Box.
All Monarch riflescope models utilize Nikon's precise, repeatable, hand turn reticle adjustments and feature the company's new Interchangeable Turret Technology system, which allows shooters to switch out turret knobs and caps for maximum convenience and versatility. This riflescope offers 1/4-MOA adjustment and can be customized with accessory target-style windage and elevation adjustment knobs and caps.
This model with magnification exceeding 10-power also features a locking side focus knob on the left side of the adjustment turret. This ergonomically-positioned control allows for precise parallax adjustment maintenance at virtually any range from 50 yards to infinity.
The Monarch 4-16x42 SF riflescope is covered by Nikon's Lifetime Full Warranty.
