Nikon Prostaff 3-9×40 Review

Last Updated: October 2016nikon prostaff 3-9x40 review

The Nikon ProStaff Rimfire 3-9 x 40 riflescope is a precise, easy to use optic scope that is great for the shooting range and for hunting in the wild. With a precise hand-turn mechanism that helps you zoom in very close to your targets and resistance to moisture that prevents fogging or dampness, this scope can handle the needs of most hunters. Overall, Nikon put a lot of work into making this an accurate and reliable riflescope and it has paid dividends.

Nikon ProStaff Features

With a 40-millimeter lens, the Nikon ProStaff has a magnification level that ranges between three and nine, which is about standard for other scopes of its kind. The objective lens allows an accurate and high-quality magnification level, and the multicoated optical system can transmit as much as 98% of the available light directly to the user. This means that there is almost no distortion or light loss, allowing you to see the target as clearly as if you were standing right next to it. The body of the scope has been filled with nitrogen and sealed with an O-ring. This keeps it from fogging up due to moisture and steam and ensures that very wet conditions won’t affect the visibility or magnification level whatsoever.

The ProStaff is a durable scope that provides high-quality optics to users. The glass of the lens is highly polished and resistant to wear, making it extremely easy to see even in less than optimal weather. Fog, rain, and poor lighting are all easily bypassed by the scope’s high light capture rate. The product has a lot of eye relief, meaning that you can use it more comfortably and in a more flexible position than many similar scopes. Durability is one of the stronger points of the Nikon ProStaff, which can handle drops, bangs, and other wear and tear with ease. If the scope does somehow break, it’s backed up by a lifetime warranty from Nikon, making this a great long-term bargain. All parts have been thoroughly tested in the field, so such problems tend to be rare.


As with many long range scopes, it takes a little bit of getting used to the Nikon ProStaff’s adjustment levels. You may need to experiment with the different magnification levels in order to find the settings you like, especially if you have familiarity with other riflescopes. The sturdy build also makes the scope slightly heavier as well, with the ProStaff weighing in several ounces heavier than its competitors. This is a conscious design choice needed to ensure a high level of durability. However, those who want a lighter weight and who feel that they are careful enough with their riflescopes may want to look at a more delicate model. It is also worth noting that this scope is designed for general users, so shooters looking for something that can be used for specialty purposes might want to look elsewhere.

What Buyers Say

The majority of people who purchased the Nikon ProStaff and provided a user review had extremely positive things to say about the product. Many of them found that the low price was deceptive and that the scope was easily comparable to much more expensive products in terms of quality. The durability and accuracy of the scope both received high marks, as did the overall usability. On the con side, some people found the Nikon ProStaff to be heavier than they would have preferred in a riflescope, although most didn’t find it too cumbersome. Those who take their target practice very seriously found that the ProStaff doesn’t quite fit all their specialty needs, but nonetheless recommended this as an excellent baseline scope.
