Searching the optics market can be a daunting task, but there are always budget options that can get you high-quality without sacrificing anything. If you’re someone who roots for the underdog, the Weaver Kaspa 3-9×40 Ballistic x scope might be the right choice for you. This scope is designed for everything from traditional hunting to competition and is the perfect choice for starters or people who want a budget scope without compromising quality.

Weaver Kaspa is the cheap and best choice, especially if you’re a beginner in the hunting world. However, many gun enthusiasts are hesitant 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 in an impartial way that will help 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 Weaver Optics.

This leading brand in the scope industry has a great reputation and respect, and manufactures the budget scope for beginners. Weaver Optics is the oldest name in American scope history, having been around since the 1930s when riflescopes were expensive and out of reach for most hunters and target shooters.

The Weaver Kaspa is a tactical riflescope that offers ballistic precision at an economical cost, making it an ideal choice for short to long-range shooting and hunting competitions. It has a one-piece construction with fully multi-coated lenses, nitrogen purged for foggy situations, and crisp 1/4 MOA adjustments for dependable accuracy.

It also features tactical turrets, illuminated BDC reticles, flip up, and protective scope caps, as well as a 30mm tube for better light transmission and a reticle dark enough to be seen against a typical background.

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

Features of Weaver Kaspa 3-9×40 Scope 

Quality of the Glass 

Upon examining 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. The color variation is not ideal, but it is acceptable. Additionally, there is no strange purple or blue refraction at the edges that can deceive you like some low-quality scopes.

In terms of light transmission, this scope is not as good as more expensive scopes. The Weaver Kaspa darkens quickly, so I would not recommend it for intensive hunting at dawn and dusk. There is no more irritating glare 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 scopes with large objective lenses are recommended.

Reticle Quality 

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

If you prefer a simple and uncluttered choice, then you can go with the Dual X reticle.

The Ballistic X reticle is an option for those who do long-range shots, as it features three elevation holdovers. It is not a dedicated long-range holdover, but it is more than enough for shooting from 150 to 250 yards. 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.

Many 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. However, it is not made to withstand heavy conditions like higher-end scopes. Additionally, it is not water-resistant, but it can withstand light rain. I do not recommend submerging or dropping water on this scope. Furthermore, it is very lightweight considering all the features it has.

I received a lifetime warranty with this scope. If the scope belongs to the original owner, Weaver will cover any defects. This warranty cannot be transferred, so make sure to keep your receipt in case of any defects.


The Weaver Kaspa 3-9×40 scope’s turrets are finger adjustable and have caps to prevent unintended adjustments. Unfortunately, its windage and elevation adjustments are not very precise or repeatable, meaning it will take more time to sight this scope.

As the turrets are not repeatable, this scope is not ideal for long range shooters. It should be noted that the quality of these turrets is to be expected for a scope at this price point.

Eye Box and Eye Relief 

The Weaver Kaspa 3-9×40 scope has an eye relief of 3.81-4.37 inches, which is a great feature. This provides more room for recoil, which is beneficial.

However, the field of view is narrower than other scopes in its price range, which is to be expected.

Ease of Use 

When I use this Weaver Kaspa, I feel very comfortable. Its turret adjustments are easy to use. It has caps to prevent any accidental adjustments, so you don’t need a coin or a screwdriver to adjust it. You can just use your finger.

The side focus is also simple to use, and the magnification ring has a knurled knob that is easy to rotate even with gloves on.

The eye relief is generous, and the scope has a fast focus eyepiece that makes it great to share with others.

Elevation and Windage Knobs 

When discussing the knobs, this scope is quite easy to use. The maximum adjustment for windage and elevation is 50 MOA. If you are familiar with adjusting a rifle scope, you will have no trouble understanding the Kaspas knobs. They are very smooth and straightforward to adjust. The most noteworthy feature of this scope is its indexing feature which allows you to zero in on specific distances.

Unfortunately, the main downside of this scope is that it is quite difficult to zero correctly. In the field, it moves a lot, making it hard to get a precise zero. This is a major issue, especially for hunters who do not have practice shots to guarantee they hit the target accurately.

Magnification and Parallax

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


If you prefer a plain matte black finish, the Weaver Kaspa scope is for you. Despite its low price, it doesn’t look like a cheap knockoff. It is lightweight and compact, making it easy to carry for a long time.

Its lens is nitrogen purged and multi-coated, making it shockproof, waterproof, and fog proof. This scope is ideal for hunting as it does not reflect sunlight. It is one of the best scopes under $300 that you can buy.

Rings and Mounting 

Mounting it on the receiver side allows for a nice cheek weld without any hassle.

However, if you want to mount it on a bench or bipod, you may have difficulty welding a good, stable cheek that doesn’t move around.

The Weaver Kaspa 3-9×40 scope comes with both low and high rings and a sun shade cap for added comfort.

Aesthetics and Style 

It has an understated dignity with its natural matte black exterior that doesn’t draw attention but looks good. The coating is designed for hunters as it is unlikely to reflect sunlight and disturb your passing game.

It is very compact and weighs less than 12 ounces, making it easy to carry. Even kids can take it to the field if you hunt with them. Weaver Optics may not be as well-known as Vortex, Leupold, or Nikon, but it is not unknown. Most experienced hunters will be familiar with the brand, whether they use the products or not.

Who the Weaver Kaspa Scope is Best For? 

If you’re wondering if this scope is right for you, the first thing to consider is who it’s designed for. Weaver is known for making some of the best tactical optics in the world, but they also have a long history of making scopes for hunting. It can be difficult to tell the difference between the two.

The good news is that the Kaspa or K series is specifically designed for hunters, target shooters, and other recreational rifle users. In addition to scopes, the Kaspa hunting series also includes tactical rings, tripods, mounts, and more. There are even binoculars in the range for those who prefer spotting scopes.
