The Nikon Monarch Gold 2.5-10x50 SF Riflescope w/BDC Reticle (6618) was designed to optimize hunting conditions to the benefit of the hunter/shooter. It features tube strength, wider windage, and a broader light path from objective to eyepiece lens than typical one-inch tube scopes. The riflescope has a wide field of view, very useable, four-times power range. It should find favor not only on heavy caliber rifles by dangerous game hunters in close and broken cover, but also by whitetail and elk hunters wanting the ultimate extreme-low-light-scope. 100% water proof, fog proof and shock proof, this 2.5-10x50 riflescope incorporates turret mounted, locking, side-focus parallax adjustments, allowing shooters to precisely focus out parallax at any known range from 50 yards to infinity. This riflescope utilizes quick-focus eyepieces with a twist and lock design to provide +/- 5 diopter adjustment and for quick and easy focus control. A rubber ring that also allows for easy gripping with gloved hands protects the end of the eyepiece. It also features Nikon's BDC (bullet drop compensating) reticle designed for easy holdover out to 600 yards (magnum calibers). The riflescope has SF (side-focus) adjustment knob to compensate for parallax which allows the shooter to get fast, inconspicuous adjustments - and reduces the overall length of this riflescope, as well. Ultra ClearCoat (UCC) optical system delivers virtually 100% anti-reflective capability. This combination of lenses and coatings allows a 95% light transmission.
