A new monarch has ascended the throne in the world of air rifles—the FX King from FX Airguns. Continually pushing boundaries and innovating, FX Airguns presents the FX King, a formidable and pure hunting rifle poised to dominate the hunting fields.

Proven Performance

At its core, the FX King inherits the proven block technology from the Panthera/Dynamic series, renowned for its exceptional power and energy delivery. While excelling as a precision pellets shooter, the FX King truly shines when firing slugs, owing to its slug-based design and innovative valving. All of this is housed within a sleek and streamlined GRS stock, tailored for both form and function.

Over-the-Barrel Plenum System

Equipped with an innovative over-the-barrel plenum system akin to other FX models, the FX King utilizes its large volume advantageously. Whether firing pellets or heavy slugs, the FX King maintains its sleek profile within a traditional sporter stock while delivering unparalleled performance.

Optimally Positioned Gauges

Featuring dual-angled high-precision Wika gauges, the FX King allows for easy monitoring of bottle and regulator pressures, even in the heat of the hunt. With this setup, you can stay informed and ready to take that crucial shot.

Quick-Tune System

Tuning a powerhouse like the FX King to suit your preferences is essential. That's why the quick-tune system is seamlessly integrated into the ergonomic GRS rifle stock, enabling swift, repeatable, and precise adjustments for optimal performance.


While maintaining its classic sporter rifle design, the FX King offers versatility with accessory Picatinny rails on both sides. Whether mounting torches, bipods, or more, the FX King is ready for any customization you desire.

Handles Pellets & Slugs

Thanks to its deep magazine design inherited from the Panthera/Dynamic series, the King effortlessly handles any ammunition up to 13mm in length. From various pellets to shorter, lighter slugs or heavier, longer slugs, the FX King delivers consistent performance.

30MOA Picatinny Scope Rail

Topping it all off is a 30MOA angled Picatinny scope rail, providing ample elevation adjustments for extended range shooting with ease.

GRS Stock

Styled in a custom-tailored GRS stock, the King exudes elegance and functionality. With three superb color options available, GRS stocks offer unmatched adjustability and ergonomic features for supreme shooting comfort.

Comes with Hard Case

For added protection during transport and storage, the FX King arrives in a durable hard case with custom-cut foam, ensuring your rifle is safeguarded at all times.
