A Review of Tasco World Class 3-9×40 Riflescope

The following is our much anticipated review of the high profiled and world renowned Tasco 3-9x40 Riflescope.

First things first, it is worth noting that: this riflescope is not only inexpensive, it is also characteristic of a 40mm objective lens as well as a 30/30 reticle all of which collectively make it stand out from the rest.

It also continues to be advertised as the most popular all-round riflescope specifically configured for deer and big game hunting. Question however remains: is it really worthy of such high praise? Well, In order to establish this, below are details of the scope to help you make a more informed personal determination, okay?

Tasco World Class 3-9×40 Riflescope Review

What Are the Scope’s Measurements?

The scope is approximately 12.75 inches long and weighs a mere 13 ounces. Its light weight is by far one of the things which makes it extremely appealing since it would not add any unnecessary extra weight to your rifle.

Another notable measurement included is the eye relief which is 3.5 inches. The scope’s parallax is set at 100 yards straight from the manufacturer. This however, is subject to further adjustments by simply screwing the front lens element either in or out followed by the refocusing of the target image.

What is the level of Magnification provided for by the Tasco World Class 3-9x40 Riflescope?

You will be glad to learn that the rifle scope is characteristic of zoomable magnification from 3X to 9X. As if that is not enough, its resolution too is quite good at all levels of magnification. What’s more, the scope has the capacity to zoom smoothly from the lowest to highest magnification.

​What is the Optics Quality on the Riflescope?

​Tasco world class 3-9x40 riflescope is characteristic of fully coated optics. It is also water resistant and fog resistant as well. In addition to the above, you should also expect to get a 30/30 reticle without any range compensation marks. To crown it all up, there is a 13.3mm exit pupil at 3X (at least 4.4mm exit pupil at the 9X magnification).

​Another good thing about the scope is the fact that the focus on the eyeball works smoothly and fast which in turn allows for a flawless focusing on the target in question at any particular time prior to zooming in for the much coveted shot each time.

Judging from the above, it goes without say that for such an inexpensive scope, the Tasco 3-9X40 works flawlessly plus it also serves as a guarantee for a crisp clear image regardless of the magnification adjustment.

​It is also worthy to note that even though the scope does not include markings for range compensation, its 30/30 reticle does serve as an accurate distance estimator. Its center section of the crosshairs is designed to span 30 inches at 100 yards with the scope itself set to 4X magnification.

The Tasco scope also has a chart included in the instruction manual which explains the various distance which the crosshair is able to cover at various different magnifications and distances. This being the case, I would highly recommend you take time to study and most importantly memorize the chart in order to get the most from your scope.

​What’s the extent of Light Gathering potential Like on the Scope?

​Light gathering on this scope is also generally good. However, it is not designed for low light conditions. This is simply because it is not illuminated plus it does not pick out details in shade areas which other expensive scopes are able to discern.

That said, it is also important to note that it does transmit enough light for a proper shot especially after the sun is up as well as before the sun goes down.

Taking into consideration all of the above, I would therefore recommend this scope for casual hunters and not for those kind of hunters who eke the most out of their hunting sessions looking to take advantage of the 30 minutes before and the 30 minutes after the set regulation.

​How wide is the scope’s Field of View?

​The scope’s field of view ranges from 15 feet (that is with the 9X magnification) all the way to 41 feet (at 3X magnification) all of which are from 100 yards. Just so you are aware, this is a very generous field of view, particularly with the 152 at 9X magnification.

This means, you can easily spot your target for instance at 3x magnification, proceed to properly focus on the target and then finally zoom in tightly for the much coveted kill shot.

​How easy is it to mount the Scope?

​You will not get any rings with this scope, however, once you have set of at least 13 rings it would be very easy to mount. Keep in mind, the 40mm objective lens might require a medium or better yet high profile set of rings in a bid to prevent the objective lens from making contact with the barrel.

Personally, I never needed any of those for any of my firearms.

​Any Tricks to help quickly and easily mount the Scope?

​One trick involves getting a medium or better yet high profiled ring to help prevent the larger objective lens from rubbing on the barrel. Personally I have never had to do that with my scope.

Your mileage for instance may vary, in fact, you should expect this especially if you have never needed medium or even high rings for use alongside your riflescope. Simply put, you might need to make use of those rings with this scope.

​How easy is the Tasco 3-9x40 Riflescope to Sight In when in use?

​I have to admit that whenever I sight into a brand new scope, I usually prefer using a laser bore sighting tool at first. I prefer it that way since it allows me to get the scope say on paper without necessarily ever having to fire any round of ammunition.

What’s more, it considerably speeds up the process of making accurate sightings while using the scope. Personally, I highly recommend the use of a laser bore sighter.

​How durable is the Tasco 3-9x40 Riflescope?

​The Tasco 3-9x40 riflescope is made from aircraft grade aluminum characteristic of fully coated optics. It is therefore fairly durable and fairly rugged as well. I also have to admit that I have previously dropped my riflescope a couple of times and there was no damage to it all.

As a matter of fact, even the adjustments to the sightings were never compromised. In addition to all of the above, it is also very important to note that: this rifle scope is not filled with nitrogen. It is therefore fog resistant as already mentioned above.

It however is still bound to fog up in the event that there is rapid temperature change hence always keep that in mind.


  • It offers an excellent field of view.
  • Its design offers good optics.
  • The distance estimator is configured in reticle.


  • The scope is characteristic of a short eye relief.
  • It is not completely fog proof.
  • There are no range compensation markers on the reticle.

Final Thoughts

Thank you for taking time to go through this review of the Tasco 3-9x40 rifle scope. As already mentioned, besides having a 30/30 reticle the scope also has an excellent bargain-bin scope that is characteristic of a variety of features which rival more expensive scopes.

Good news is, at its current price, you are guaranteed rock solid performance. Personally, I rate it at 5/5 for the simple fact that it performs consistently under almost any circumstance also because it feature a distance estimator which is most ideal for hunting without a rangefinder.
