Weaver Kaspa 3-9x40mm Review

Magnification Range

The 3-9x magnification range of the Kaspa scope allows shooters to adjust the zoom level according to their specific needs. The low end of the magnification range, at 3x, provides a wider field of view, making it ideal for close-quarters shooting or tracking fast-moving targets. This lower magnification setting aids in target acquisition and situational awareness.

On the other hand, the high end of the magnification range, at 9x, enables shooters to zoom in on targets at medium distances, offering more precise aiming and increased target detail. This higher magnification setting is particularly useful for accurate shot placement and engaging targets at medium ranges, such as hunting in open fields or precision shooting scenarios.

The ability to switch between these magnification levels provides shooters with the flexibility to adapt to different shooting environments, making the Weaver optic suitable for a wide range of applications.

Objective Lens Size

This Weaver scope is equipped with a 40mm objective lens. The objective lens is responsible for gathering incoming light and light transmission to the eyepiece, thus determining the brightness and clarity of the sight picture. With a 40mm objective lens, the Kaspa optic offers a good balance between light transmission and overall size. There are other models in the Kaspa series that larger objective lenses, like 44 mm and 50 mm. A larger 44 mm lens allows more light to enter the scope, resulting in a brighter image, especially in low light conditions. 

Additionally, a larger objective lens can provide a wider exit pupil, which refers to the beam of light that reaches the shooter’s eye. This larger exit pupil makes it easier for the shooter to quickly acquire the target and maintain a consistent sight picture, even when there is slight movement or eye positioning variance.


The Kaspa 3-9x40mm scope offers two popular reticle options: the Dual X reticle and the Ballistic X reticle. Let’s explore each of these reticles in more detail:

Dual-X Reticle:

The Dual-X reticle is a classic and widely used reticle design. It features a simple crosshair with thick outer lines that taper to thinner crosshairs towards the center. The thin center portion allows for precise aiming at the target, while the thicker outer lines aid in quick target acquisition and sighting in various lighting conditions. The Dual-X reticle provides shooters with a clean and uncluttered sight picture, making it particularly useful for general hunting and target shooting scenarios. Its simplicity allows for fast target acquisition, especially when engaging moving targets or when speed is crucial. The Dual-X reticle’s straightforward design also ensures minimal distraction, allowing shooters to focus on their target without unnecessary visual complexity.

Ballistic X Reticle

The Ballistic X reticle is designed to assist shooters in compensating for bullet drop. It typically features additional 3 hash marks or aiming points below the center crosshair, allowing for precise holdovers at different distances. The Ballistic reticle provides shooters with a versatile aiming solution, particularly useful for those engaging targets at varying distances or in windy conditions. By using the hash marks or aiming points, shooters can easily adjust their aim to compensate for bullet drop at different ranges. This helps increase accuracy and ensures consistent shot placement. The Ballistic-X reticle’s additional aiming points allow for quick holdover adjustments, eliminating the need for manual adjustments or turret dialing in the field. 

Glass Quality

The glass quality of a rifle scope plays a crucial role in determining the clarity, brightness, and overall visual performance of the scope. High-quality scopes, including the Weaver Kaspa series, often feature multiple layers of anti-reflective coatings on the lenses. These coatings help reduce glare, improve light transmission, and enhance image clarity. Fully multi coated lenses, where all air-to-glass surfaces are coated, are particularly desirable as they maximize light transmission and minimize reflections.

Eye Relief

Eye Relief

The eye relief of this Weaver optic falls within the range of 3.81 to 4.37 inches. An eye relief range of 3.81 to 4.37 inches indicates that the distance between the rear lens of the scope and your eye can be adjusted within that range to achieve a full, unobstructed sight picture.

Having an adjustable eye relief range offers shooters flexibility in finding the most comfortable position for their eye without compromising the field of view or the scope’s performance. This is particularly important for shooters using firearms with different recoil levels or for those who prefer a specific eye relief distance.

A longer eye relief allows for more comfortable shooting, especially when using firearms with heavy recoil, as it helps to prevent the scope from impacting your brow or causing injury. It also provides flexibility in head positioning and accommodates shooters who wear eyeglasses or have varying eye relief preferences. It’s important to note that the eye relief range can vary depending on the magnification setting of the scope. Typically, lower magnifications offer a wider eye relief range, while higher magnifications may have a narrower range.


The Weaver Kaspa 3-9x40mm scope features a 1-inch tube diameter, which suggests that it is designed to be mounted using a 1-inch scope mount.

The mount size of a rifle scope refers to the specific diameter of the scope tube and the corresponding scope rings or mounts required to attach the scope to the firearm. In the case of the Weaver Kaspa 3-9x40mm scope, it has a 1-inch tube, which is a common size for many scopes.

To properly mount this Weaver scope, you would need to select a set of scope rings or mounts designed to accommodate a 1-inch tube. These rings or mounts should match the mounting system or rail on your firearm to ensure a secure and stable attachment. When selecting scope rings or mounts, you should consider factors like ring height, material, and style (e.g., Weaver-style, Picatinny) that are compatible with your firearm’s platform. This will ensure proper alignment, clearance, and optimal performance of the scope.

The Kaspa 3-9x40mm scope is designed with a Weaver-style mount. This mount system is a popular and widely used mounting system for rifles. It features a specific type of rail or base that allows for secure attachment of the scope to the firearm. The Weaver-style attachment utilizes a series of slots on the mounting rail, which provide multiple points of contact for the scope rings or mounts. This design offers flexibility in positioning the scope along the rail and allows for easy installation and removal of the scope without losing zero.

Weaver-style rails are commonly found on various rifles, shotguns, and handguns, making it easier to find compatible attachments.


The durability of the Weaver Kaspa scope is an important consideration for shooters and hunters who rely on their equipment in various shooting conditions. High-quality scopes, including those from reputable manufacturers like Weaver, are typically constructed using durable materials such as aircraft-grade aluminum or other rugged alloys.
