FX Panthera Hunter

FX Panthera Hunter 300cc Single Bottle

The FX Panthera Hunter 300cc is the dedicated hunting oriented version of the revolutionary FX Panthera platform a purpose built slug rifle that redefines airgun performance with generational innovations. Engineered from the ground up for precision, efficiency, and real-world hunting, this single bottle model combines a sleek, over the barrel 300cc carbon fibre tank with the same groundbreaking Dynamic Block and Plenum technology that has made the Panthera a game changer.

The Dynamic Block features a compact one piece high power/short-impulse valve for immense airflow, while the Dynamic Plenum wraps around the barrel providing consistent regulated pressure, exceptional barrel stiffness, and the flexibility to use multiple plenum sizes (Micro, Macro 47cc, Magnum XL 156cc) to perfectly match caliber and power. The latest AMP MKII Regulator ensures ultra-tight velocity consistency, with 10-shot strings showing SDs as low as 1.0–2.0 fps and ES of 3–4 fps unmatched in airguns.

The FX Superior STX barrel (Heavy liner with carbon fibre sleeve on longer models) is optimised for heavy slugs, while the 500 model uses the standard STX liner for pellets and lighter slugs. The Quick Tune System allows fast valve, hammer, and regulator adjustments to find perfect harmonic balance.

The competition-ready stock includes a 14.75" Arca rail with M-LOK sections and barricade block, fully adjustable buttstock and ambidextrous cheekpiece, and balance enhancing options (M-LOK weights, internal barrel weights). A 300cc carbon fibre bottle with rear Foster QD fill, 20 MOA Picatinny rail, zero angle grip, and reversible ambidextrous sidelever complete the package. Dual angled manometers display bottle and plenum pressure.
