Introducing the FX King: Your Ultimate Hunting Companion

(Note: Scope & rings pictured are sold separately. RH image used for display purposes.)

Experience the reign of power with the all-new FX King by FX Airguns. Continuously pushing boundaries and innovating, the FX King stands as a testament to excellence in hunting rifles.

Built on a Proven Block The FX King inherits the proven block of the Panthera/Dynamic series, delivering remarkable power and energy. While exceptional with pellets, its true prowess lies in shooting slugs, thanks to its innovative valving and slug-based design. All housed within a sleek and stylish GRS stock.

Over-the-Barrel Plenum System Equipped with a large over-the-barrel plenum system, akin to other FX models, the FX King maximizes volume advantageously. Whether shooting pellets or heavy slugs, this rifle maintains its sleek profile in a traditional sporter stock.

Optimized Gauges Placement High-precision Wika gauges, positioned at dual angles, monitor bottle and regulator pressures. Stay informed during your hunts, even from the shouldered position, ensuring you never miss a crucial shot.

Quick-Tune System Tailor your FX King to perfection with the seamless integration of the quick-tune system into the ergonomic GRS rifle stock. Make adjustments swiftly, repeatedly, and precisely to suit your preferences.

Accessory-Ready Design While boasting a classic sporter rifle design, the FX King accommodates accessories effortlessly. Accessory Picatinny rails on both sides offer the flexibility to mount torches, bipods, and more.

Versatile Ammunition Handling With a deep magazine design inspired by the Panthera/Dynamic series, the King effortlessly handles various ammunition types, including pellets and slugs up to 13mm in length.

Enhanced Scope Rail Topped with a 30MOA angled Picatinny scope rail, the FX King provides increased usable elevation adjustments, enabling effortless long-distance shooting.

Crafted in GRS Stock Excellence The King rests in a custom-tailored GRS stock, akin to a fine-tailored suit befitting royalty. Available in three stunning color options, GRS stocks boast unparalleled adjustability, ergonomic features, and shooting comfort.

Includes Hard Case Your FX King arrives in a premium hard case with custom-cut foam, ensuring secure transportation and storage of your prized rifle.
