800mm Barrel Tension Kit with Slug Ready Heavy Liner
To push the boundaries of what small-bore slugs can do, FX is introducing an 800mm Slug Tensioned Barrel for the FX Impact. This barrel will allow the FX Impact to shoot heavier slugs at the speeds needed to create a higher BC which will allow the Impact to shoot at further distances. This barrel has achieved a first in the airgun world, an airgun shooting the same caliber and same grain weight bullet as a standard firearm. The 800mm Slug Tensioned Barrel, when combined with a Power Block and Tungsten hammer weight equipped FX Impact, will shoot a .22 Caliber 40gr slug at speeds of 1030 ft/s. The common weight and speed shot by many professional .22LR competition shooters. All FX Tensioned Barrels allow the shooter to use a moderator. 1/2” UNF threads come standard on all but the .35 Calibers, which use an M18x1 thread.
Note: The tensioned barrel is not really needed for pellet shooters because pellet shooting uses much less pressure and produces less movement to the barrel. The existing STX barrels are more than rigid enough to cater to standard pellets and their associated speeds (except for the .35 caliber that does benefit from it).

When installing the tension nut, tighten until the nut is flush with the carbon fiber housing, then tighten an additional quarter turn. Additional torque is not needed. Note: The tensioned barrel is not really needed for those shooting pellets as pellets use less pressure and produces less movement to the barrel (except for the .35 caliber that does benefit from the tensioner).
*In order to get the advertised velocities (40gr. slugs @ 1040 fps) you will need an Impact with Power Block, 720 Power Plenum, Pin Probe & Tungsten Hammer Weight.
The advancement of slug shooting and the enhancements to the FX Impact have shooters wanting to use heavier slugs at faster speeds. This requires a more rigid barrel to handle the additional energy and vibrations created by these projectiles. The new FX Tensioned Barrel System adds the firmness needed to let you reach the potential of the FX Impact with heavy slugs, all while maintaining the extreme accuracy everyone expects from an FX Airgun. Conceived and created by the famed airgun engineer Hein Frommann, who perfected it through a global collaboration with Johan & Fredrik Axelsson (Sweden), Matt Dubber & Roelf Vorster (South Africa) & Ernest Rowe (USA).
The result is really showing off the brain trust at FX Airguns. From a barrel harmonics perspective, the tensioner system reduces the amplitude of barrel movement which results in better accuracy and more consistency. Secondarily the rigidness of the barrel becomes more temperature stable and will further hold zero regardless of conditions and to handle knocks to the barrel during hunting, PRS courses, etc.
