Introducing the FX King: Reign Supreme in the Hunt

A monarch among rifles, the all-new FX King from FX Airguns continues to redefine limits and innovate in myriad ways. Engineered as a potent and pure hunting companion, the FX King stands poised to dominate the hunting grounds.

Built on a Proven Foundation

At its core, the FX King inherits the battle-tested block of the Panthera/Dynamic series, renowned for its formidable power and energy delivery. While its prowess with pellets is undeniable, where the FX King truly shines is in shooting slugs, owing to its slug-oriented design and cutting-edge valving—all encased in a sleek, custom-tailored GRS stock.

Over-the-Barrel Plenum Advantage

Equipped with the innovative over-the-barrel plenum system found in other FX models, the FX King leverages its voluminous plenum to full advantage. Whether you're firing pellets or hefty slugs, the FX King handles both with finesse, all while maintaining its traditional sporter stock aesthetic.

Precision Gauges at Your Fingertips

Dual-angled, high-precision Wika gauges are strategically positioned to monitor bottle and regulator pressures, ensuring you stay informed even during shoulder-mounted shots while out in the field—a feature designed to guarantee you never miss a crucial opportunity.

Quick-Tune for Personalization

A powerhouse like the FX King demands customization, which is why the quick-tune system is seamlessly integrated into the ergonomic GRS rifle stock. With quick, repeatable, and precise adjustments, tailor your FX King to suit your preferences effortlessly.

Accessory-Ready Design

Despite its classic sporter rifle profile, the FX King caters to your accessory needs with Picatinny rails on both sides, facilitating the attachment of torches, bipods, and more.

Versatility in Ammunition Handling

With its deep magazine design inherited from the Panthera/Dynamic series, the King accommodates various ammunition types up to 13mm in length, from any pellet variety to shorter, lighter slugs or heavier, longer slugs—handling them all with ease.

Enhanced Scope Mounting Capability

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

Luxurious GRS Stock

Nestled in a custom-tailored GRS stock, the King exudes regal elegance, available in three exquisite color options. Crafted by Norwegian stock-making artisans, GRS stocks offer unparalleled adjustability and comfort, ensuring the King reigns supreme.

Complete with Hard Case

Delivered in a sturdy hard case with custom-cut foam padding, the FX King arrives safeguarded and snug, ready for transport and storage.
