Nikon Prostaff 3-9×40 Review

Nikon is the industry leader in making the best rifle scope. They have been producing superior performing rifle scopes for many decades in a price range that will be within your budget. Many of our riflescope reviews cover Nikon products because they are simply the best riflescopes on the market.

The Nikon ProStaff 3-9x40mm Target EFR rifle scope is a highly accurate, fast-targeting scope that provides a user with the fast-focusing capabilities of a short range sight and the versatility of a variable zoom scope. Nikon makes professional-grade rifle scopes that have a fast-focus eyepiece. This eyepiece allows the user to bring the precision reticle into full focus nearly the instant that the user aligns their eye with the scope.

Nikon riflescopes are equipped with optics that are fully multi-coated. Animals are made more visible during hunting because of the high rate of light transmission that this scope provides. It does not matter if you are stalking your game at dawn or dusk, you will always have high brightness images provided by this scope.

This scope has been specially engineered to be used with air rifle and .22 LR ammunition. However, it is also able to be used with every type of ammunition by utilizing the Spot On ballistic match technology that has been integrated into the scope. Zero-reset turrets have been installed by Nikon in their line of ProStaff rifle scopes. These turrets help to eliminate any of the guess work that is typically necessary when a person is forced to make adjustments for elevation and windage. This is done by specially tailoring the scope to your rifle and load out.

The ProStaff 3-9x40mm also comes complete with elevation and windage knobs with an adjustment rate of 1/4 MOA. This allows the user to tailor each of his or her shots to their exact location. Just like many other Nikon products, this scope is O-ring sealed and filled with nitrogen. The scope can also be used in hunting conditions that are extremely wet and demanding. This is because it is completely fog proof and waterproof.

With fast return-to-zero capabilities, the ability to focus quickly and a wide variable magnification range, this Nikon riflescope is a powerful and versatile tool that has been expertly crafted with top quality materials. Any person involved in hunting or shooting activities of any kind should not be without it.
