Description
FX Wildcat MKIII Compact
Every so often, a precision air rifle emerges that shifts expectations. The FX Wildcat MKIII Compact is exactly that kind of innovation — a carefully refined bullpup platform that blends cutting-edge design with effortless control. Compact in size yet commanding in presence, this PCP rifle brings balance, accuracy, and sophistication together for both hunters and target shooters.
Unlike traditional airguns that demand compromise, the Wildcat MKIII Compact offers seamless performance in every field scenario. It’s meticulously engineered to deliver unrivalled power within a lightweight frame, ensuring ease of manoeuvrability without sacrificing stability. Whether positioned on the range bench or stalking quietly through dense woodland, users experience precision that feels almost intuitive
Designed for Modern Shooters
From its origin, the FX Wildcat line has embodied Swedish innovation. Each iteration has raised the standard for airgun ergonomics, airflow efficiency, and trigger precision. The MKIII Compact version continues this evolution, refined with a superior regulator, improved valve system, and enhanced air delivery. These upgrades not only improve shot consistency but also extend usable air per fill — ideal for extended shooting sessions or longer hunting expeditions.
This rifle doesn’t just perform; it connects with its user. The adjustable components, ambidextrous layout, and thoughtfully placed controls ensure that every shot feels natural and comfortable. Left-handed shooters enjoy the same intuitive operation as right-handed users, reflecting FX’s dedication to inclusive design principles.
Build, Craftsmanship, and Ergonomics
Compact Powerhouse Construction
Built around a sleek bullpup configuration, the FX Wildcat MKIII Compact measures under 700 mm in total length, yet houses a 500 mm Smooth Twist X barrel — a hallmark of FX’s engineering. This design allows for high muzzle velocity and excellent pellet stability, even in windy outdoor conditions.
The rifle’s body is crafted from high-grade aluminium and durable synthetic materials, reducing weight to approximately 2.8 kg. That balance between strength and lightness makes it equally suited for standing, prone, or kneeling positions. The result is a firearm that encourages precision without fatigue.
Attention to Detail
FX Airguns is known for precision machining, and the Wildcat MKIII Compact is no exception. Every curve, cut, and contour has been designed to serve a purpose. The ergonomic stock provides a solid yet comfortable cheek weld, while the soft-touch coating ensures a secure grip even in damp weather.
An enlarged trigger guard offers better accessibility when wearing gloves — a thoughtful feature for hunters in colder climates. The seamless integration of the side-lever mechanism ensures smooth, reliable cycling with minimal movement. It’s a rifle that feels like an extension of the shooter, not just a tool.
Advanced Air System and Regulation
At the heart of the FX Wildcat MKIII Compact lies its most remarkable feature: the refined AMP Regulator. This Adjustable Match Precision Regulator allows consistent air pressure delivery to the valve, ensuring every shot leaves the barrel with near-identical velocity.
Benefits of the AMP Regulator
-
Maintains consistent FPS spread for extreme accuracy
-
Improves air efficiency, increasing shot count per fill
-
Reduces pressure fluctuations that affect long-range grouping
Combined with the improved power plenum and upgraded valve, the system delivers smoother airflow and enhanced shot-to-shot consistency. The result is a rifle capable of producing tight groupings well beyond 50 metres, with minimal variation — exactly what both hunters and competition shooters demand.
Performance in the Field
Target Shooting Precision
For target shooters, the FX Wildcat MKIII Compact transforms every session into a masterclass in control. The adjustable trigger offers a crisp break, while the regulated airflow produces a flat trajectory even with heavier pellets. The Smooth Twist X barrel system allows shooters to experiment with different liners and calibres, customising the rifle for personal preference or competitive advantage.
Transitioning between distances becomes effortless, supported by the rifle’s exceptional balance and light recoil. Shooters experience less fatigue and greater shot repeatability — a key factor in achieving consistent high-score results.
Hunting Capability
In the field, stealth and speed are everything. The Wildcat MKIII Compact’s compact form and quiet operation make it ideal for close-range hunting or woodland stalking. The integrated shroud and internal moderator suppress report noise to a discreet whisper, helping hunters maintain their advantage.
The rifle’s high air efficiency means fewer refills during long outings. Paired with its quick-handling design, it allows for fast follow-up shots when needed. Every feature is optimised for confidence in real-world hunting situations — whether pursuing rabbits, corvids, or small game across open countryside.
The Genius Behind FX’s Barrel Technology
The hallmark of every FX Airgun is its barrel innovation, and the FX Wildcat MKIII Compact carries this legacy forward with precision engineering that transforms air into accuracy. At the heart of this design lies the Smooth Twist X (STX) Barrel System, a modular concept that redefines what adaptability means for airgun shooters.
Smooth Twist X: Engineering Mastery
Unlike conventional rifling methods, the STX system employs a carefully engineered twist rate applied from the outside of the barrel. This external formation ensures minimal friction and perfect alignment, allowing pellets to accelerate smoothly while maintaining their optimal shape. The result is tighter groupings, improved ballistic consistency, and remarkable downrange stability — even at extended distances.
FX’s barrel liners can be swapped easily, enabling shooters to tune their rifle for specific calibres, pellet types, or slugs. Hunters can optimise for high-energy performance, while target shooters may choose liners that favour precision and reduced drag. This customisation flexibility reflects the Wildcat MKIII Compact’s role as not merely a rifle, but an evolving system.
Customisation, Tuning, and Personalisation
The FX Wildcat MKIII Compact offers shooters more than static excellence; it offers creative control. The rifle’s design encourages tuning and experimentation — key elements for enthusiasts who seek the perfect balance between power, precision, and efficiency.
Power and Regulator Adjustments
The AMP regulator allows for fine-tuned pressure control, letting shooters optimise their rifle’s power output for different projectiles. Combined with the adjustable hammer spring, users can tailor the firing characteristics for maximum accuracy or energy efficiency depending on field conditions.
For example:
-

The plenum is the part that contains the regulated air used for the shot. A larger plenum gives greater power potential and optimizes the rifle for lower regulator pressure.FX Air Gun - Rear Power Adjuster
On the back of the action is now an adjustment wheel for the hammer spring that easily adjusts the power in 8 steps (0-7).
This alows the user to optimize the Wildcat for different ammunition types and use-casesAt position 0, a small Allen key can be inserted into the adjusting wheel to fine-tune the hammer spring pressure at a micro level.FX Air Gun - Adjustable AMP regulator
The regulator ensures that the rifle constantly uses the same pressure with every shot.
As a result, rifles with a regulator are significantly more accurate than models without this part.The AMP regulator from FX is adjustable in pressure, which means that this rifle can be adjusted for multiple uses in conjunction with the power adjuster.
For example, a higher regulator pressure gives more power, and a lower pressure gives more shots per fill. - Smooth Twist X borrel system
Like many other FX rifles, the Wildcat MK3 is equipped with the STX barrel system.
These barrels contain interchangeable liners where the pulls and fields are rolled in externally.
Thanks to this system, the barrels and liners with different pitches and lengths can be exchanged for different uses.
By default, this rifle is equipped with the STX Superior liner, which is optimized for pellets and light slugs - Dual transferport
The transferport is the part that allows the air to enter the barrel when shooting.
By loosening the barrel and rotating it 180 degrees, it can switch between using the smaller “pellet” port, or the larger bride-style “slug” port.FX Wildcat MKIII Compact
