The New FX Integrated Harmonic Barrel Tuner
The FX Integrated Harmonic Barrel Tuner offers both vibration reduction and tuning features that will have you obtaining new apex of accuracy from your FX Airgun. The shroud of the Harmonic Barrel Tuner first works to lessen vibration of the barrel, making the harmonic signature of the barrel quieter, more subdued, and controllable.
The final touch is found in the integrated rotating moving weight located on the end of the shroud. Made from a specifically selected metallic alloy, this allows the moving weight to have enough mass to affect the weight distribution of the overall barrel system. Shooters will find that even the smallest increment of rotation adjustment of the tuner weight by only a few thousands of an inch can change the accuracy of your gun, especially when shooting medium to long range distances.
