FX Airguns has made available the Harmonic Tuner for all brands and styles of airguns now! The Harmonic tuner has been removed from the FX Impact-specific shroud, and made into a stand alone unit, to provide the accuracy benefits to any airgun barrel with 1/2" UNF threads!
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!
When using on other FX models with a STX system, such as the Maverick or Wildcat MKIII, combine the tuner with the FX Carbon Fiber Liner Sleeves to maximize stability and massively reduce harmonic resonance!
