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

Introducing the all-new FX King from FX Airguns, where innovation meets power. As a leader in the industry, FX continues to redefine hunting rifles, and the FX King is no exception.

Built on a Proven Foundation The FX King inherits the trusted block design from the Panthera/Dynamic series, ensuring exceptional power and performance. While it excels in pellet shooting, its true prowess shines with slugs, thanks to its specialized design and advanced valving, all housed within a sleek GRS stock.

Revolutionary Plenum System Featuring an innovative over-the-barrel plenum system, akin to other FX models, the FX King maximizes volume for unparalleled performance. Whether you prefer pellets or heavy slugs, this rifle delivers, maintaining its sleek profile in a traditional sporter stock.

Precision Monitoring on the Fly Dual-angled high-precision Wika gauges are strategically positioned to monitor bottle and regulator pressures, even during intense hunts. Stay informed and focused, ensuring every shot counts.

Easy Customization with Quick-Tune System Tailor the FX King to your preferences with the quick-tune system seamlessly integrated into the ergonomic GRS stock. Make precise adjustments on the fly, ensuring optimal performance every time.

Ready for Accessories Despite its classic sporter design, the FX King features accessory Picatinny rails on both sides, perfect for mounting torches, bipods, and more, enhancing its versatility in the field.

Versatile Ammunition Handling With a deep magazine design inherited from the Panthera/Dynamic series, the FX King effortlessly handles various ammunition types, including pellets and slugs up to 13mm in length, ensuring adaptability to any hunting situation.

Enhanced Scope Mounting Topped with a 30MOA angled Picatinny scope rail, the FX King offers increased elevation adjustments for extended range shooting with ease and precision.

Crafted for Comfort and Style The FX King is adorned in a custom-tailored GRS stock, available in three exquisite color options. Crafted by renowned Norwegian stock-maker GRS, it boasts unparalleled adjustability and ergonomic features, ensuring supreme shooting comfort and control.

Protected for Travel Your FX King arrives in a durable hard case with custom-cut foam, providing secure transport and storage for your prized rifle.
