Weaver Kaspa is the cheap and best choice, especially if you’re a beginner in the hunting world. However, several gun enthusiasts are very reluctant to commit to cheap scopes because they think cheap means lower quality.

Is this a low-quality scope? In this article, I’ll explain all details of the Weaver Kaspa scope impartial way that helps you make the correct decision. 

Let’s dive in!

What is Weaver Kaspa?

Are you the person who judges a scope by its cover? You should definitely check out the Weaver. 

Weaver is one of the leading brands in the scope industry. It has a great reputation and respect and manufactures the budget scope for beginners. Moreover Weaver Optics is the oldest name in American scope history.

If you want to buy a spotting scope from a brand that knows the terrain, it doesn’t get better than Weaver Optics. This brand has been around since the 1930s when riflescopes were expensive, and out of reach for most hunters and target shooters. 

Even the least scopes would run from $50 to $70, which was a huge amount of money at that time. 

Weaver Optics’ brainchild was William R. Weaver, who wanted to alter something up and made a handmade gun that went on the market for $19.

The Weaver Kaspa is a tactical riflescope that offers ballistic precision at an economic cost. It is an ideal choice for short to long-range shooting and hunting competitions. 

Its one piece construction comes with fully multi-coated lenses. The sturdy lenses are nitrogen purged so that we can view the target in a foggy situation.

This Weaver Kaspa scope features crisp 1/4 MOA adjustments to deliver dependable accuracy. Apart from these aspects, it lets more rigidity and more adjustments for accuracy. 

In addition, this tactical scope also features tactical turrets, illuminated BDC reticles, flip up, and protective scope caps. To deliver better light transmission, this Weaver has a 30mm tube. The reticle is dark enough to be seen against a typical background on regular outlines.

In this depth review, I’ll tell you why this Weaver Kaspa might be the best starter scope for all you hunting enthusiasts out there. 

Specifications of Weaver Kaspa 3-9x40 Scope

Features of Weaver Kaspa 3-9×40 Scope 

Quality of the Glass 

Looking at the Weaver Kaspa 3-9×40 scope, I found its image to be as clear as many popular brand scopes in the same price range, such as the Nikon Buckmaster II. Color variation is not that good but acceptable.

Moreover, there’s no weird purple or blue refraction at the edges that can fool you like, some low-quality scopes.

In terms of light transmission, this scope is not as good as more expensive scopes. Weaver Kaspa darkens very quickly, so I’m not suggested for intensive hunting at dawn and dusk. There is no more annoying burning when the sun is in front of you and behind you.

If you do a lot of hunting in low light, high end scopes or large objective lens scopes are suggested.

Reticle Quality 

The great feature of this scope is its reticle. It is sharp and easy to spot and provides two reticles to choose from. 

  • Dual X – same as a simple duplex reticle
  • Ballistic X – BDC reticle

If you’re a person who likes simple and no clutter choice, then you can go with a dual X reticle. While the Ballistic X reticle is an option for those who do long range shots as it features three elevation holdovers. 

It’s not a dedicated long range holdover but is more than enough for 150 to 250 yards shooting. This is one of the best advanced scopes for long range shooting from the budget weaver brand.

The glass etched reticle is not illuminated, but the 40mm objective lens delivers plenty of light. 

A lot of people experience very serious holdovers with this scope. I found the same in my tests. I found myself aiming several inches off target to get a shot. 


The Weaver Kaspa 3-9×40 scope has a one piece tube that is very durable and works well in normal conditions. But when I check thoroughly, this scope is not made to withstand heavy conditions like high end scopes. Also, since it is not water resistant, it can withstand light rain very well. I do not recommend submerging or dropping water in this scope. What’s more, it’s very lightweight considering all the features it has. 

I got the lifetime warranty with this scope. When the scope belongs to the original owner, the weaver will cover any defects. This warranty cannot be transferred, so make sure you keep your receipt in case of any defects.


Weaver kaspa 3-9×40 scope’s turrets are finger adjustable, and caps stop unintended adjustments. Unfortunately, its windage and elevation adjustments are not that precise nor repeatable. It means it will take more time to sight this scope. 

As the turrets are not repeatable, the Weaver Kaspa will not be best for long range shooters. Note that the quality of these turrets is expected for scope around this price point.

Eye Box and Eye Relief 

Weaver kaspa 3-9×40 scope eye relief is 3.81-4.37 inches. This is definitely a notable feature on the Weaver Kaspa. More wiggle room for a kickback is usually an advantage. 

The field of view is somewhat narrower than other similar scopes, but that’s to be expected in its low price bracket.

Ease of Use 

When I use this Weaver Kaspa, I feel very comfortable. Its feature turret adjustments are simple to handle. 

It features caps to prevent accidental adjustments. You don’t even need the help of a coin or a screwdriver to fix its turrets.

Just use your finger to adjust it. The side focus is simple to use.

The magnification ring has a knurled knob that is smooth to rotate even with your gloves on.

The eye relief is generous, and the scope features a fast focus eyepiece that would be grateful if you share this scope with others. 

Elevation and Windage Knobs 

When we talk about the knobs, this scope is pretty simple to use. The maximum adjustment for windage and elevation is 50 MOA. 

If you already know how to adjust a rifle scope, you will easily understand these Kaspas knobs. They’re very smooth and simple to adjust. The highlighting feature of this scope is its indexing feature which lets you zero in on particular yardages. 

However, the main disadvantage with this scope is it’s quite difficult to zero properly. Out in the field, it moves a lot. Zero is unbelievable. This is a significant problem, especially for all hunters who don’t have practice shots to ensure they hit the target accurately.

Magnification and Parallax

The parallax on this scope is fixed at 100 yards. The magnification range starts from 3x to 9x, which lets you effectively use the scope in most conditions.


If you are a person who likes a plain matte black finishing, the Weaver Kaspa scope is for you. Even though this scope comes at a cheap price, it doesn’t look like a cheap knockoff. As it is a lightweight and compact scope, you will easily carry it out for a long time. Its lens is nitrogen purged and multi-coated , so it is shockproof, waterproof, and fog proof. 

I suggest this scope for hunting as it doesn’t reflect sunlight. This is one of the best scopes under $300 that you can buy. 

Rings and Mounting 

Let’s talk about the mounting. In terms of the Weaver Kaspa 3-9×40, it is very easy to mount. Mounting it on the receiver side lets for a nice cheek weld without any hassle. 

However, if you want to mount it on a bench or bipod, you may get some trouble welding a good cheek that’s stable and doesn’t move all over the place.

To give more comfort, the Weaver Kaspa 3-9×40 scope comes with both low and high rings and a sun shade cap. 

Aesthetics and Style 

There is an understated dignity when using the Weaver Kaspa 3-9×40. It is designed with a natural matte black exterior that doesn’t catch the eye but certainly doesn’t look bad.

The coating is designed for hunters as it is unlikely to reflect sunlight or disturb your passing turkey or deer. It doesn’t look like a flimsy, lower end scope, though it doesn’t have much extra flair to boast of.

It’s also very compact and weighs less than 12 ounces, making it easy to carry around with you. Even kids can take it to the field if you hunt with them.

While Weaver Optics is not as famous as Vortex, Leupold, or Nikon, it is not unknown. Most experienced hunters will be knowledgeable about the brand, whether they use the products or not.

Who the Weaver Kaspa Scope is Best For? 

To decide whether this scope is something you should check out or not, the foremost thing you should be surprised about is who it’s designed for.

That’s normal, as Weaver has been the best scopes in the world of tactical optics. However, Weaver also has been used for hunting over the years, and it can occasionally be difficult to differentiate one from the other.

The great news for hunters is that this scope is specially made for that type of use. The whole Kaspa or K series is made for hunters, target shooters, and other recreational rifle users. 

Apart from that, the Kaspa hunting series provides many tactical rings,  riflescopes, tripods, mounts, and more. There are also binoculars within the range for those who like spotting scopes.
