FX Panthera MKII 700 .22 Cal

The FX Panthera MKII in .22 caliber with the 700mm barrel is the next evolution of FX's competition-bred Dynamic Block platform. Unlike a general-purpose air rifle, the Panthera was designed from the ground up as a dedicated precision slug rifle — built to deliver .22LR-style consistency and straight-back recoil, with the power and tunability that have made it a serious contender across PRS, hunting, and benchrest disciplines.

Why Shooters Choose the Panthera MKII

• Built for slugs, not adapted for them. The Dynamic Block, over-the-barrel Dynamic Plenum, and Superior Heavy STX liner are purpose-engineered around slug performance — not a pellet rifle retrofitted to handle them.
• Genuinely ambidextrous. Reversible side-lever and reversible cheekpiece mean left- and right-handed shooters get the same level of fit and function.
• Next-level rigidity. The MKII's reinforced front stock design grips the block at multiple points, virtually eliminating flex and improving shot-to-shot repeatability under recoil.
• One trigger, three personalities. The Quick Set Trigger lets you reconfigure trigger character to match your discipline — without swapping parts.
• Competition pedigree. Originally built to win .22LR-style precision rifle competitions, the Panthera platform has since proven itself across PRS, hunting, and benchrest.
• At-a-glance pressure monitoring. Dual manometers mean you always know your air state without breaking position.
