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

Introducing the reigning monarch of air rifles: the all-new FX King. With relentless innovation and a commitment to pushing boundaries, FX Airguns has crafted a rifle that stands poised to dominate the hunting fields.

Built on a Proven Foundation At its core, the FX King inherits the renowned block of the Panthera/Dynamic series, renowned for its power and precision. While it excels in pellet shooting, its true prowess lies in firing slugs, thanks to its innovative valving and slug-based design. All of this is elegantly housed within a custom-tailored GRS stock, combining performance with aesthetics.

Over-the-Barrel Plenum Power Equipped with the large over-the-barrel plenum system found in other FX models, the FX King harnesses this innovative technology to deliver exceptional power and versatility. Whether you're shooting pellets or heavy slugs, this rifle maintains its sleek profile and exceptional performance.

Precision Monitoring with Dual Gauges Dual-angled high-precision Wika gauges are strategically positioned to monitor bottle and regulator pressures, allowing you to stay informed while shouldering your rifle. Never miss a crucial shot with this advanced monitoring system.

Quick-Tune for Personalized Performance The FX King features a seamless quick-tune system integrated into the ergonomic GRS rifle stock, enabling quick, repeatable, and precise adjustments tailored to your preferences.

Accessory-Ready Design While maintaining its classic sporter rifle design, the FX King is equipped with accessory Picatinny rails on both sides, allowing you to easily mount torches, bipods, and more.

Versatile Ammunition Handling With its deep magazine design inherited from the Panthera/Dynamic series, the King effortlessly handles various types of ammunition, accommodating pellets of any kind as well as shorter, lighter slugs or heavier, longer ones.

30MOA Picatinny Scope Rail Topped with a 30MOA angled Picatinny scope rail, the FX King offers enhanced elevation adjustments, allowing you to confidently take aim at longer distances with ease.

Crafted for Comfort: GRS Stock Dressed in a custom-tailored GRS stock, available in three stunning color options, the FX King delivers unparalleled comfort and ergonomic support. With features like tool-less adjustments, a broad fore-end, and an offset and angled grip, this rifle ensures an exceptional shooting experience.

Protected in Transit: Hard Case Included Your FX King arrives in a sturdy hard case with custom-cut foam, providing optimal protection during transportation and storage.
