Cheap Nikon 6476 6 - 18 x 40 Buckmasters Side-focus Target Dot Matte Riflescope (Electronics) Price

The precision-ground and polished optical glass is coated with Nikon's exclusive Brightvue coating that allows 92 percent light transmission, giving you super clarity and high resolution. Positive, audible, manual 0.125 MOA (Minute of Angle) windage and elevation adjustments eliminate reticle creep or backlash. The scope features Nikon's specially designed side-focus parallax adjustment for even greater targeting ease. Just set the adjustment at the distance you will be shooting from and your targeting will be clear and accurate.

The Nikon 6476 features an adjustable 6x to 18x magnification and a large, 40 millimeter objective lens diameter, giving the scope an exit pupil size of 6.7 to 2.2 millimeters, depending on magnification. A 6x magnification setting on this scope makes the image appear six times larger than with the eye alone with an exit pupil of 8.9 millimeters. In other words, objects at 100 yards appear to be only 17 yards away through a 6x scope and the Nikon 6476 would work great at this magnification in fair light. At the 18x magnification setting, the exit pupil would be reduced to 2.2 millimeters. The Nikon 6476 is a full-sized scope with an adjustable magnification and exit pupil, making it an excellent choice for fair light targeting as well as long distance targeting in full light.

About Exit Pupil Size
The size of the exit pupil for a riflescope is determined by dividing the objective lens diameter by the magnification rating. The human eye pupil diameter ranges from 2 to 7 millimeters, depending on the amount of light. For proper light gathering potential, the diameter of the scope's exit pupil must be equal to or greater than the diameter of your eye pupil at the light level you will be using the scope. If you're working in low light, your exit pupil size will be of greater importance. With an adjustable 6.7 to 2.2 millimeter exit pupil, the Nikon 6476 6-18 x 40 Buckmasters side-focus target dot matte riflescope is an excellent choice for hunting in fair light or long distance hunting in full light.
