FX Impact M3 Integrated Harmonic Barrel Tuner 700MM

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. Combined with the new FX Carbon Fiber Liner Sleeve, it also stiffens the barrel system which further lowers the barrel’s harmonic amplitude throughout the entire shot cycle. Both of these factors combined, create tighter shot groups, but are only part of the overall barrel tuning 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).
