FX Dynamic – Hunting-Focused PCP Air Rifle

Experience the power and innovation of the Panthera platform, engineered specifically for hunting applications. The FX Dynamic is a pneumatic air rifle that goes beyond competition—it's purpose-built for the field.

Featuring cutting-edge airgun technology, the Dynamic delivers greater air capacity and versatile configurations compared to its competition-oriented sibling, the FX Panthera. A .35 caliber option generates up to 200 ft-lbs of energy while maintaining FX's renowned accuracy and precision.

Dynamic Block Technology

This dedicated slug rifle features the innovative Dynamic breech block—a compact, one-piece design with a short-impulse, high-power balanced valve. Extremely efficient yet capable of delivering tremendous, precise airflow with every shot. When properly tuned, expect low single-digit standard deviations.

Over-The-Barrel Power Plenum

An FX-exclusive design, this revolutionary plenum system allows multiple lengths to match your caliber and power requirements. The plenum also applies consistent regulated pressure to enhance barrel rigidity.

Includes tailored cut-out hard case (except VP versions).
