The FX Dynamic is a pneumatic rifle built for more than competition. Its a rifle that wants to hunt. Harnessing technology at the forefront of airgun performance, the Dynamic brings higher air capacity and configurations than its competition focused sister rifle, the FX Panthera. The Dynamic also includes a .35 caliber option that will allow up to 200 ft lbs of energy while maintaining world-class FX accuracy and precision. This purpose-built slug rifle utilizes its namesake breech block. The Dynamic block has a one-piece, compact, short-impulse/high-power balanced valve which is both extremely efficient while also allowing a tremendous and precise amount of air with each shot. Tuned properly the rifle will achieve low single digit standard deviations, one of just many advantages the FX Dynamic offers. The block is fed by the cutting-edge Over-The-Barrel Power Plenum, a design only found with FX. This allows multiple plenum lengths to be employed to match the caliber and power of the rifle. This plenum also applies consistent regulated pressure to strengthen barrel rigidity.
