FX Panthera 500


Available on back-order

Categories: , , ,


The FX Panthera is unlike any rifle FX Airguns has made before. It is a dedicated slug rifle, purpose-built with precision competition in mind and complete with airgun innovation that continues the FX Airguns tradition of pushing the boundaries of airgun performance.

The Panthera includes technology that is a generational leap-forward for an airgun. It begins with the new Dynamic Block, a new breech block designed from the ground up for performance slug shooting. The Dynamic Block utilizes a compact one-piece valve. This High-Power / Short-Impulse Valve is extremely efficient while allowing an immense and precise flow of air.

The plenum feeding the Panthera is revolutionary and the first of its kind. The Dynamic Plenum is an over-the-barrel plenum which provides a consistent regulated pressurized plenum around the barrel, adding incredible stiffness to the barrel as well as allowing multiple plenum lengths to be employed to match the calibre and power of the rifle.

The results of the Dynamic Breech & Plenum are extraordinary! Testing has yielded constant 10 shot strings with standard deviations in the low 1.0–2.0 range with extreme spreads as low as 3-4.

The Panthera stock is designed for competition. It features a 14.75” long Arca rail complete with M-LOK sections and a barricade block nestled next to the breech. Achieve an ideal balance point by adding external M-LOK compatible weights or internal FX Barrel Weights that attach under the shroud. The Panthera further fits the shooter using a fully adjustable buttstock and an adjustable cheekpiece that is also ambidextrous.

The Panthera 500 uses the standard FX Superior STX barrel liner that shoots both pellets and light weight slugs. The “500” has a 500mm (19.7”) barrel with a 250 BAR fill pressure giving a .22 cal. 112 shots to the fill.

The FX Panthera will forever change the precision rifle world. It feels and shoots like a precision 22LR, enjoying straight back recoil, but with laser sharp precision and accuracy only found with an FX Airgun!
