FX Harmonic Barrel Tuner (Removable 1/2" UNF)

This tuner takes the core rotating tuning weight from the Integrated Shroud and places it in a removable unit for use with any 1⁄2” UNF threaded airgun! It also includes and utilizes the air stripping effects of the caliber specific muzzle threads.

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.
