Collection: Panthera / Dynamic / King

Upgrade and maintain your rifle with FX Panthera accessories, plus parts built for the closely related FX Dynamic and King. This collection gathers the bottle adapters, caliber change kits, maintenance parts, and handling upgrades that fit these platforms — sourced from FX Airguns and trusted specialists including Huma-Air and Saber Tactical, and stocked in Canada.

Whether you are extending air capacity, switching calibre, or keeping a high-end PCP sealed and shooting consistently, the parts here are matched to the Panthera, Dynamic, and King:

• Air capacity — front and quick-change bottle adapters and FX DoubleAir adapter kits for more shots per fill.
• Caliber change — caliber change kits, V2 dual-hole transfer ports, and high-flow pin probes to run .177 through .30.
• Maintenance — O-ring kits and full repair kits to reseal the rifle and hold air.
• Handling and ergonomics — recoil pads, cheek pieces, rail and barrel weights, bag riders, slot covers, and spare magazines.

What fits the Panthera, Dynamic, and King

Because these three platforms share so much, many parts cross over between them — but fit is not universal, so confirm a part is listed for your exact rifle before ordering. Looking for parts beyond this category? Browse the full FX Airguns accessories range, explore complete PCP air rifles if you are still choosing a platform, and dial in performance with FX custom parts and tuning, aftermarket regulators, and the right rifle scopes and optics to match your build.
