Unrivaled Power and Precision At the heart of the FX King lies the proven block inherited from the esteemed Panthera/Dynamic series.

Whether you prefer pellets or heavy slugs, this rifle effortlessly adapts while maintaining its sleek profile in a traditional sporter stock.

Seamless Tuning for Personalized Performance Unlock the full potential of the FX King with its quick-tune system seamlessly integrated into the ergonomic GRS rifle stock. Enjoy quick, repeatable, and precise adjustments tailored to your preferences.

Versatile Accessory Mounting Options While embodying the classic sporter rifle design, the FX King offers modern convenience with accessory Picatinny rails on both sides. Customize your rifle with torches, bipods, and more to suit your hunting style.

Adaptable to Any Ammunition With its deep magazine design inherited from the Panthera/Dynamic series, the King effortlessly handles a variety of ammunition, including pellets and slugs up to 13mm in length. From lightweight pellets to heavy slugs, this rifle delivers exceptional performance across the board.

Elevated Precision with 30MOA Picatinny Scope Rail Topping it all off is a 30MOA angled Picatinny scope rail, providing enhanced elevation adjustments for precision shooting at longer distances with ease.

Crafted for Royalty: GRS STOCK Embrace luxury with the custom-tailored GRS stock, available in three exquisite color options. Designed by Norwegian stock-making company GRS, renowned for its highly adjustable ergonomic laminate stocks, the FX King ensures unparalleled shooting comfort and style.
