The FX Integrated Harmonic Barrel Tuner offers both dampening and
tuning features jointly developed between Chris Turek of UpNorthAirgunner
and Fredrik Axelsson of FX Airguns.

The result is not just a harmonic barrel tuner, but a complete tuning device that incorporates many barrel dampening qualities to result in some of the best accuracy you can achieve from an airgun.

The shroud of the Integrated Tuner is made of high-grade carbon fiber. The carbon fiber adds dampening qualities, stiffness, and exponentially more de-resonating qualities when compared to aluminum. Carbon fiber is also hardly affected thermally. The thermal heat expansion of a hot sun on a standard thin aluminum shroud can heat and create POI shifts through thermal flex. Carbon fiber, on the other hand, is affected 1/10th as much as aluminum, thus drastically reducing this effect.

Dampening is further enhanced by de-resonating rings that have
been engineered into the base of the shroud that squeeze the barrel and
further reduce vibrations through the barrel.

These above features, when combined with the recently released FX
Carbon Fiber Liner Sleeve, absolutely stiffen the barrel system which further
lowers the barrel’s harmonic amplitude (or whip) throughout the entire shot
cycle. Both factors combined create tighter shot groups, but are only part of
the overall barrel tuning that this FX system brings.

The core of the Tuner is its integrated rotating running weight, located on the end of the shroud. Made from a specifically selected metallic alloy; this allows the running weight to have enough mass to affect the weight distribution of the overall barrel system. Shooters will find that even the smallest amount of rotating adjustment of the tuner weight by only a few thousands of an inch can change how the
rifle shoots. The brilliance of the weight is a tool-free design. The weight has been designed to hold its position without the need of grub screws!

Each Harmonic Tuner comes with caliber specific ends (.22, .25 and .30) that thread into the tuner allowing for the addition of a moderator.
