Unleash Precision with the FX Panthera: The Ultimate Slug Rifle for Competition

Introducing the FX Panthera: a groundbreaking slug rifle engineered for precision competition, representing a quantum leap in FX Airguns' legacy and redefining airgun performance.

Revolutionary Dynamic Block: The Panthera features the innovative Dynamic Block, meticulously designed for slug shooting performance. Its compact one-piece valve, the High-Power / Short-Impulse Valve, ensures exceptional efficiency and precise airflow for unparalleled performance.

Cutting-Edge Plenum Design: Setting new industry standards, the Dynamic Plenum feeds the Panthera, offering a regulated pressurized plenum around the barrel. This design enhances barrel rigidity and allows for precise pressure adjustments. With three plenum sizes - Micro, Macro, and Magnum XL - tailored to various calibers and power levels, the Panthera delivers extraordinary results.

Unmatched Precision: Extensive testing demonstrates consistent 10-shot strings with minimal standard deviations and extreme spreads. Paired with the world-class FX Superior STX barrel using premium slugs, the Panthera guarantees competition-winning accuracy, even surpassing .22LR precision shooters' expectations.

Competition-Ready Stock: Designed for competition, the Panthera features a 14.75” long Arca rail with M-LOK sections, ideal for customization. Its fully adjustable buttstock and ambidextrous cheekpiece ensure a personalized fit for every shooter.

Exceptional Features: Equipped with a 300cc carbon fiber bottle for air source, the Panthera boasts a larger breech to accommodate projectiles up to 13mm in length. Additional features include the Quick Tune System, a 20MOA Picatinny scope rail, and an ambidextrous side-lever cocking handle.

Versatile Configurations: Available in three configurations - Panthera 700, Panthera 600, and Panthera 500 - each tailored to different barrel lengths and shooting preferences. While the Panthera 600 and 700 come standard with the FX Superior Heavy STX barrel liner for slug shooting, the Panthera 500 offers versatility with the standard FX Superior STX barrel liner, supporting both pellets and lightweight slugs.

Customization Options: Enhance your rifle with optional accessories like a bag rider, barrel weights, and offset M-LOK weights. The Panthera's versatility and precision will revolutionize the precision rifle world, offering straight-back recoil and unmatched accuracy, characteristic of FX Airguns.

Advanced Features: Featuring the AMP MkII Regulator, externally adjustable settings, and micro and macro adjustment of hammer spring tension, the Panthera ensures optimal performance and ease of use.

Experience the future of precision shooting with the FX Panthera - a rifle that combines precision, power, and versatility like never before.
