FX Impact STX Slug Tensioned Barrel Kit
Rigidity. Accuracy. Built for Slugs.
The Tensioned Barrel System is engineered for shooters pushing the limits of slug performance. Designed to handle heavier projectiles and higher velocities, it delivers the rigidity and consistency needed for precision shooting at distance.
Overview
As slug shooting evolves, increased energy and velocity demand a more stable platform. This system uses a tensioned design to reduce barrel movement and harmonics, resulting in improved accuracy and repeatability—especially with heavy slugs.
Developed through global collaboration, it represents a refined approach to maximizing performance from modern platforms.
