The FX Panthera MkII 700 is a 6.35 mm PCP air rifle developed for long-range precision shooting with slug ammunition. Its 700 mm FX Superior STX barrel system, large 163 cc Dynamic Plenum and adjustable AMP MkII regulator allow the setup to be matched to the chosen projectile and velocity. Depending on the configuration, tune and ammunition, power can reach approximately 145–150 joules.
The MkII model uses a reinforced aluminium forend to increase overall rigidity. Reduced flex helps the rifle maintain consistent alignment during demanding precision shooting. A full-length Arca-Swiss rail runs along the underside for attaching a bipod or tripod, while the M-LOK slots accept accessories and balancing weights.
The Quick Set Trigger can be adjusted for PRS, benchrest or hunting-style use without removing the trigger guard. The Quick Tune System provides separate macro and micro adjustments for hammer spring preload, making tested settings easy to record and reproduce.
The Dynamic Block features an enlarged loading port that accepts slugs up to 13 mm long. Its High Power / Short Impulse valve delivers a rapid flow of air, while the over-barrel plenum supports stable pressure delivery and adds rigidity around the barrel.
A rear-mounted 300 cc carbon-fibre bottle provides the air supply and fills to 250 bar through a Foster quick-disconnect fitting. Separate Wika gauges display bottle and regulator pressure. An adjustable cheekpiece and butt plate, reversible sidelever and integrated 30 MOA Picatinny rail help the shooter create a practical setup for long-range optics and individual shooting positions.
