Description

The FX Dynamic Express 700 (DYN-550306-022-00) is a purpose-built slug rifle. Its defining feature is the Dynamic Block, which houses a high-power, short-impulse balanced valve. This valve is designed for extreme air-flow efficiency, allowing it to push heavy .22 caliber slugs at high velocities with remarkably low standard deviations.

The 700mm barrel is paired with the Magnum XL Plenum, which wraps around the barrel. This “over-the-barrel” design not only provides a massive 156cc of regulated air for high-energy shots but also increases the structural rigidity of the barrel system. Unlike the Panthera’s front bottle, the Express moves the 480cc carbon fiber tank to the rear, serving as the buttstock, which improves the balance for off-hand shooting in hunting scenarios.
