Introducing the FX King: Reign Supreme in the Hunting Fields

The FX King from FX Airguns represents a pinnacle in innovation and performance, redefining the standards for hunting rifles. With a focus on power and precision, this rifle is poised to dominate every hunting expedition it encounters.

Proven Performance: Built upon the proven block of the Panthera/Dynamic series, the FX King delivers unparalleled power and energy. While it excels in pellet shooting, its design is optimized for slugs, boasting innovative valving for exceptional performance. Complemented by a sleek GRS stock, the FX King seamlessly combines power with elegance.

Over-the-Barrel Plenum System: Equipped with an innovative over-the-barrel plenum system, reminiscent of other FX models, the FX King maximizes air volume for superior performance. Whether shooting pellets or heavy slugs, this system ensures consistent power delivery while maintaining a traditional sporter stock aesthetic.

Optimized Gauges: Featuring dual-angled high-precision Wika gauges, the FX King allows shooters to monitor bottle and regulator pressures with ease. This ensures precise pressure management, even during intense hunting scenarios, guaranteeing every shot counts.

Quick-Tune System: With the integrated quick-tune system, tuning the FX King to your preferences is effortless. Seamlessly integrated into the ergonomic GRS rifle stock, adjustments are quick, repeatable, and precise, empowering shooters to fine-tune their rifle for optimal performance.

Accessory-Ready Design: Despite its classic sporter rifle design, the FX King offers versatility for mounting accessories. With Picatinny rails on both sides, shooters can easily attach torches, bipods, and more, enhancing their hunting experience.

Versatile Ammunition Handling: Thanks to its deep magazine design, inherited from the Panthera/Dynamic series, the FX King effortlessly handles various types of ammunition, including pellets and slugs of up to 13 mm in length. From lightweight pellets to heavy slugs, this rifle delivers consistent accuracy and power.

30MOA Picatinny Scope Rail: Completing its feature set is a 30MOA angled Picatinny scope rail, enabling shooters to make precise elevation adjustments for extended range shooting with ease.

GRS Stock: Crafted by Norwegian stock-making company GRS, the custom-tailored GRS stock offers unparalleled comfort and adjustability. With features like tool-less adjustments, broad fore-end, and ergonomic grip, the GRS stock ensures a superior shooting experience.

Hard Case Included: Your FX King comes packaged in a durable hard case with custom-cut foam, providing maximum protection during transportation and storage.
