The one accessory that will have the biggest impact on the air gunning industry is the new FX Integrated Harmonic Barrel Tuner. This integrated shroud system offers new features that will change your tuning process and give you a level of precision control never before available to an airgun.

The FX Integrated Harmonic Barrel Tuner offers both dampening and tuning features that will have you obtaining new heights of accuracy from your FX Airgun. FX Airguns teamed up with Chris Turek of Up North Air gunner to bring this exciting technology to an FX Airgun.

The science behind barrel harmonics and internal ballistics has been debated and analysed for years. Though there are still unknowns, what is known is that barrel harmonics exist in all guns from a .177 break barrel airgun all the way up to a .50 cal Barret. These barrel harmonics are observable and are now adjustable for repeatability. This is the art of barrel tuning.

The shroud of the Harmonic Barrel Tuner first works to dampen the barrel, making the harmonic signature of the barrel quieter, more subdued, and controllable. This, when combined with the new FX Carbon Fiber Liner Sleeve, also stiffen the barrel system which further lowers the barrels harmonic amplitude (or whip) throughout the entire shot cycle. Both of these factors combined create tighter shot groups, but are only part of the overall barrel tuning that the FX system brings.

The finishing touch is found in the 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 your gun shoots groups, especially when shooting medium to long range distances.

The beauty and genius of the FX Integrated Harmonic Barrel Tuner is realized with the single variable testing and tuning found both with the shroud system and internally with the new FX Impact M3. This intersection of beauty (form) and precision (function) will change the sport of precision airguns to the next level.

The FX Integrated Harmonic Barrel Tuner will be offered in 600mm, 700mm & 800mm shroud lengths for both the Impact M3 as well as the FX Maverick.
