Nikon PROSTAFF Target EFR 3-9×40 Review


The Nikon PROSTAFF target EFR 3-9×40 rifle scope comes with some of the very efficient features that make target shooting more comfortable and easier. The multicoated optics, zero reset turret, and BDC reticle are the featured advantages of this scope. The scope also comes with some other features to make it very popular items for the outdoor enthusiasts, especially the hunters.

In this Nikon PROSTAFF target EFR 3-9×40 Review, we will discuss much more on this scope with advantages and also some downsides. Check out those below.


Multicoated optical system

This matte black Nikon PROSTAFF EFR scope has 95% light transmission which makes the glass incredibly bright and sharp. While different types of hunting like, deer hunting, duck hunting, one can easily get to the target with its optical system.

That’s why the image is very clear even at low light when some of the shy rodents show up in your yard after daytime.

Zero-reset turret with spring-loaded adjustment knob

Another wonderful feature of Nikon PROSTAFF scope is you do not need to use a tool to zero the turrets. Just simply lift, turn, then reset it to zero. Yeah, that simple. And usually, it only takes just 2 shots to get it zeroed in.

Waterproof, Fog proof, Shockproof performance

With the Nitrogen-filled, O-ring-sealed housing the Nikon PROSTAFF is reliably waterproof and fog proof. And the best part is it can handle the recoil shock and doesn’t lose its zero as long as you want.

 BDC reticle of Nikon PROSTAFF

One of the most important features of this Nikon PROSTAFF is that the amazing reticle does not cover the targets. Because the Precision Reticle is designed to draw the eye into the small dot at the reticle center, which is just large enough to create a focal point without covering a small target.

And another Interesting feature I did not know it had, that the Precision Reticle does somewhat illuminate or lighten a bit when you look at a dark target.

Quick-focus eyepiece

This versatile and reliable Nikon PROSTAFF scope focuses and zooms very easily. From my experiences I can tell you that I wear glasses and most scopes I have used in the past, I have had to prop the glasses on my forehead to get a clear view through the scope in certain situations. But With this Nikon scope, it does not matter glasses on or off. That’s why it’s always a go for you with this scope.

Precise Hand-turn 1/4-inch Click Adjustments

Generally, I think 1/4 MOA per click of this Nikon PROSTAFF is more than enough for any rim-fire practice. And I gradually love the AO (Adjustable Objective) function. Without it, indoor range shooting might be difficult. Also, this features makes hunting in sports on in forest little more safer than ever. The safe hunting is not only the advantage of this option though.

Most indoor range max distance is 25 yards, but the parallax free range for most other scopes is usually from 50 yards and above, that’s why anything less than 50 yards will be blurred. So, if a squirrel is standing out less than 50 yards from you, then the quick AO is a MUST-HAVE function for you in indoor range shooting.

Nikon Spot on software

Another plus point of this Nikon PROSTAFF is the Spot-On software program that is provided by Nikon which will greatly assist you in determining how your particular cartridge should respond under different magnification settings, environmental conditions, sight heights, etc.
