FX Panthera 500mm Air Rifle
The FX Panthera 500mm Air Rifle is a high-performance sub-12 ft·lbs PCP rifle built for precision and adaptability. Featuring FX’s Dynamic Block system with 62 cc Macro Plenum, it delivers consistent, regulated shots. The 500 mm Superior STX barrel ensures elite accuracy, while the modular ambidextrous chassis, adjustable match trigger, and reversible sidelever offer full customisation. With dual pressure gauges, Side-Shot magazine, and Picatinny/Arca-Swiss mounting, the Panthera is engineered for serious target shooters demanding control, consistency, and cutting-edge design.
The FX Panthera 500mm Air Rifle is a cutting-edge, competition-bred PCP platform, purpose-built for precision performance within UK sub-12 ft·lbs limits. Available in both .177 and .22 calibres, the Panthera blends tactical innovation with refined engineering, making it a top choice for discerning target shooters.
At the heart of the rifle lies FX’s Dynamic Block system, a high-efficiency regulated valve unit with Short Impulse technology for fast, consistent air delivery. Paired with the 62 cc Macro Plenum and a 300 cc rear-mounted carbon fibre bottle, the system ensures superb shot-to-shot consistency, even with lightweight slugs or longer pellets.
The rifle is equipped with a 500 mm FX Superior STX barrel, pellet-optimised and housed within a modular design that allows for future liner upgrades to tune accuracy to your exact requirements. This barrel delivers elite precision, fully maximising the Panthera’s sub-12 ft·lbs potential.
Housed in a modular ambidextrous tactical chassis, the Panthera features an AR-style grip, adjustable cheekpiece, and adjustable buttstock for a fully customised shooting fit. The reversible sidelever action ensures smooth cycling whether you shoot left- or right-handed, while dual angled pressure gauges offer real-time monitoring of both regulator and bottle pressure at a glance.
Each rifle includes a high-capacity Side-Shot magazine, 21 shots in .177 calibre or 18 in .22, with room for longer projectiles. The two-stage match-grade trigger is fully adjustable for pull weight, sear engagement, and travel, and is compatible with the FX Quick Tune system for unrivalled control.
For mounting optics and accessories, the Panthera features a 20 MOA Picatinny top rail for elevated scope alignment, along with Arca-Swiss and M-LOK mounting options on the forend for tripods, bipods, and other shooting aids.
With a fill pressure of up to 250 BAR, the Panthera delivers approximately 100 shots per fill in .177 and 112 shots per fill in .22, all within legal UK power limits. Measuring 965 mm overall and weighing just 3.5 kg unscoped, this air rifle offers a superb balance of performance, adjustability, and precision engineering.
