This integrated shroud system offers new features that will change your tuning process and give
you a level of precision and control never before available to an airgun.

The FX Integrated Harmonic Barrel Tuner offers both dampening and tunning features that will have you obtaining new heights of accuracy from your FX Airgun. Suitable for the FX Maverick and Impact M3

The science behind barrel harmonics and internal ballistics has been debated and analyzed 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 caliber Barret. These barrel harmonics are observable and are now adjustable for repeatability. This is the true art of barrel tuning.

The specially designed 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 barrel’s 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 tunning that this 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).

Carbon shroud.

Comes with inserts for .177/22, .25 and .30 to allow silencer to be added to the end of the shroud.
