As an avid recreational shooter and occasional small game hunter, the need for reliable and accurate optics is paramount. While high-end scopes offer exceptional performance, their price point can be prohibitive for many. This led me to explore more budget-friendly options, and the CVLIFE JackalHowl F02 AO Rifle Scope caught my attention due to its advertised features, particularly the adjustable objective (AO) for parallax correction – a feature not always common in this price range. After several range sessions and practical applications, I present a detailed technical review of this Second Focal Plane (SFP) scope.
First Impressions and Unboxing
Upon receiving the CVLIFE JackalHowl F02, the packaging was functional, if not overly premium. The scope was securely nestled within a molded insert, accompanied by the promised accessories: two high-profile 20mm Picatinny scope rings, a set of flip-up lens covers, a small Allen wrench for mounting, a basic lens cleaning cloth, and a concise instruction manual.
My initial handling of the scope revealed a surprisingly solid build. The matte black anodized finish on the one-piece aircraft-grade aluminum tube felt robust and free of obvious manufacturing defects. The turrets had a tactile click to them, and the adjustable objective ring rotated smoothly, albeit with a slight resistance that suggests it will hold its position well. The included scope rings, while basic, appeared adequately machined for secure mounting.
Optical Performance – The Core Functionality
The primary function of any rifle scope is to provide a clear and magnified view of the target. The JackalHowl F02 boasts a variable 2-7x magnification range coupled with a 32mm objective lens. This range is generally considered versatile for various shooting scenarios, from close-range airgun use to medium-range rimfire and even some centerfire applications.
Clarity and Sharpness
Evaluating the optical clarity across the magnification range is crucial. At the lower end of the spectrum (2x), the image presented was reasonably clear and sharp. The fully multicoated green lenses did a decent job of transmitting light, providing a bright enough image for daytime shooting. Edge-to-edge clarity was acceptable, with a slight softening becoming noticeable towards the periphery of the field of view.
As the magnification was increased towards the maximum of 7x, a subtle decrease in overall image sharpness became apparent, which is not uncommon in budget-oriented optics. However, the image remained usable for target identification and aiming. Critical focus became more sensitive at higher magnifications, necessitating precise adjustment of the eyepiece diopter to achieve optimal clarity for my eye.
Light Transmission and Brightness
The 32mm objective lens, coupled with the fully multicoated lenses, facilitated adequate light transmission during well-lit conditions. The image remained sufficiently bright for comfortable shooting during daylight hours. However, in lower light conditions, such as dusk or dawn, the smaller objective lens and potentially less sophisticated coatings compared to premium optics became more apparent, resulting in a dimmer image. This is a trade-off often encountered in scopes at this price point.
Chromatic Aberration (Color Fringing)
Chromatic aberration, or color fringing, is a common optical artifact. In the JackalHowl F02, I observed a minimal amount of color fringing, primarily around high-contrast edges, especially when viewing targets against a bright sky at higher magnifications. While present, it was not severe enough to significantly detract from the overall viewing experience during typical use.
Field of View
The manufacturer specifies a “Field Of View: 5 Yards.” This is misleading and likely refers to the minimum parallax adjustment distance, not the angular field of view. The actual angular field of view decreases as magnification increases. At 2x, the field of view was reasonably wide, allowing for easier target acquisition. However, at 7x, the field of view narrowed considerably, which is typical for variable magnification scopes. This narrower field of view can make tracking moving targets or quickly locating targets in a broader area more challenging. While the exact angular values were not provided by the manufacturer, the observed change was consistent with expectations for a 2-7x scope.
Parallax Adjustment (Adjustable Objective – AO)
The inclusion of an adjustable objective (AO) is a significant feature for a scope in this price range. Parallax occurs when the reticle image and the target image are not focused on the same optical plane. This results in apparent movement of the reticle on the target if the shooter’s eye position changes slightly behind the scope. The AO allows the user to adjust the objective lens to bring both the reticle and the target into sharp focus on the same plane for a specific distance, thereby minimizing parallax error.
The AO ring on the JackalHowl F02 rotated smoothly and was clearly marked with approximate distance indicators (though these are often less precise than on higher-end scopes). By adjusting the AO to match the estimated distance to the target, I observed a noticeable improvement in both image sharpness and the stability of the reticle on the target as my eye position varied. This feature is particularly beneficial for precision shooting at known distances and is a significant advantage over fixed-parallax scopes in this category. The minimum focusing distance achieved with the AO was indeed close to the advertised 5 yards, making it suitable for airgun and very close-range rimfire applications.
Reticle and Targeting
The CVLIFE JackalHowl F02 features a Bullet Drop Compensation (BDC) reticle in the Second Focal Plane (SFP).
Reticle Design
The specific pattern of the BDC reticle was not detailed by the manufacturer, but it appeared to be a variant of a duplex reticle with additional hash marks or dots below the center crosshair. These markings are intended to provide holdover points for different distances, compensating for bullet drop. The fineness of the reticle lines was generally well-balanced; they were thin enough not to obscure small targets excessively, even at higher magnifications, yet thick enough to remain visible against various backgrounds in decent lighting conditions.
Second Focal Plane (SFP)
Being an SFP reticle means that the size of the reticle remains constant throughout the magnification range. This has implications for the BDC markings. The holdover points will only be accurate at a specific magnification level, typically the highest magnification (7x in this case). Shooters need to be aware of this and either use the scope at the designated magnification for accurate BDC holdovers or learn the subtensions at other magnifications through range testing.
Reticle Usability
The reticle was generally easy to see and use for basic aiming. However, without specific subtension values provided by the manufacturer, the BDC markings require significant range time and experimentation with the specific ammunition and firearm to determine their accurate holdover values at different distances. This is a common limitation of non-premium BDC reticles. The lack of illumination also means that reticle visibility can be reduced in very low light conditions.
Turrets and Adjustments
The JackalHowl F02 features capped, finger-adjustable turrets for windage and elevation.
Click Value and Tactility:
The turrets offer 1/4 MOA (Minute of Angle) adjustments per click. The clicks were both tactile and audible, providing clear feedback when making adjustments. This is essential for precise zeroing and making controlled adjustments in the field. The resistance of the turrets was adequate, preventing accidental adjustments.
Adjustment Range and Tracking
The total internal adjustment range for windage and elevation was not specified by the manufacturer. During the initial zeroing process, I found sufficient adjustment range to achieve a proper zero for my .22LR rifle. However, the consistency and accuracy of the tracking over larger adjustments would require more extensive testing, such as a “box test,” which was beyond the scope of my initial evaluation. Based on the feel of the clicks, I anticipate reasonable tracking accuracy for typical hunting and recreational shooting within moderate adjustment ranges.
Zero Reset Feature
The turrets feature a zero-reset capability. After achieving a proper zero, the outer cap of the turret can be loosened, allowing the user to rotate the indicator marks to align with the “0” without altering the actual internal adjustments. This is a convenient feature for quickly returning to the established zero after making temporary adjustments in the field.
Build Quality and Durability
The manufacturer emphasizes the scope’s robust construction, claiming it is crafted from a single piece of aircraft-grade aluminum tube and has undergone shockproof testing.
Material and Construction
The one-piece aluminum tube does contribute to the overall sturdiness of the scope. The anodized matte black finish appeared durable and resistant to minor scratches during normal handling. The fit and finish were generally acceptable for a scope in this price bracket.
Shockproof Performance
While I did not subject the scope to extreme shock tests, it held its zero through several range sessions with a .22LR rifle, which produces minimal recoil. The manufacturer’s claim of withstanding over 500 rounds of 1000G impact suggests a decent level of shock resistance, making it suitable for use on airguns, rimfire rifles, and potentially some lighter-recoiling centerfire platforms.
Waterproof and Fogproof Performance
The scope is advertised as O-ring sealed and nitrogen purged for waterproof and fogproof performance. During my testing, which included exposure to light rain and significant temperature changes, I did not observe any internal fogging or water ingress. This is a crucial feature for maintaining a clear sight picture in various environmental conditions.
Mounting and Compatibility
The inclusion of 20mm high-profile scope rings is a convenient addition.
Included Scope Rings
The provided rings were functional and adequately machined for securing the scope to a Picatinny rail. The high-profile design offered sufficient clearance for the 32mm objective lens on my test rifle. However, users with different mounting systems or preferences for ring height may still need to purchase separate rings.
Mounting Process
Mounting the scope using the included rings was a straightforward process using the provided Allen wrench. The rings tightened securely onto the Picatinny rail, providing a stable platform for the scope. Proper leveling of the reticle during mounting is still essential for accurate shooting.
Compatibility
The manufacturer lists compatibility with a wide range of firearms, including airsoft, rimfire (.22LR, .17 HMR, .22 pellets), and even some centerfire calibers (5.56, .223). Based on my experience, the 2-7x magnification range and adjustable parallax make it well-suited for airguns and rimfire rifles used for plinking, target shooting, and small game hunting at moderate ranges. While it can be used on AR-platform rifles chambered in 5.56 or .223, the lower maximum magnification might limit its effectiveness for longer-range engagements typically associated with these calibers.
Overall Impression and Value
The CVLIFE JackalHowl F02 AO Rifle Scope presents a compelling option for budget-conscious shooters seeking a scope with the added benefit of adjustable parallax. Its build quality is surprisingly robust for its price point, and the optical performance is generally acceptable for recreational shooting and small game hunting within moderate ranges. The tactile turrets with a zero-reset feature are also welcome additions.
However, there are limitations. The optical clarity and brightness are not on par with higher-end optics, particularly at higher magnifications and in low light conditions. The BDC reticle lacks specific subtension information, requiring user experimentation for accurate holdovers. The included scope rings are functional but may not be ideal for all setups.
