FX FX STX Superior Heavy Liner $109.99
LINER SALES ARE FINAL - NON RETUNABLE PRODUCT   *This liner is highly recommended in order to get the best results with heavier grain slugs. In our preliminary testing we have found this liner performs well will slugs needing a faster twist rate to stabilize.  The groundbreaking Smooth Twist X barrel liner has been further perfected. FX Airguns proudly introduces the new FX Superior Smooth Twist X Barrel Liner (or FX Superior STX). The new Superior STX barrel liners are still created using the patented way of pressing the rifling into the barrel from the outside; but this is now done with a higher degree of precision, lower tolerance, and some other slight modifications that result in a superior liner to the standard STX liners. RESULTS ARE NOT GUARANTEED
FX FX Impact | STX Slug Tensioned Barrel Kit from $349.99
*SHIPS WITH HEAVY SUPERIOR SLUG LINER 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. 800mm Barrel 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. 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. 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 800mm Impact with Power Block, 720 Power Plenum, Pin Probe & Tungsten Hammer Weight.
FX FX Impact | STX Barrel Kit (Smooth Twist X Superior) from $299.99
*SHIPS WITH STX - Smooth Twist X Superior LINER*PROBE INCLUDED*MAGAZINES NOT INCLUDED The Smooth Twist X Barrel is a fully rifled barrel liner. All barrel kits now ship with the STX Superior Liner. FX’s proprietary process of imparting the inner rifling of the barrel from the outside of the steel tubing leaves a flawlessly smooth finished rifling inside the bore. This in turn increases the accuracy of the projectile drastically and makes this a highly coveted barrel for any air gun enthusiast. These barrel kits will include the barrel, shroud & probe for the selected caliber. This barrel is housed in the Interchangeable Barrel system allowing the shooter to swap and change barrel liners of various twist rates, bore specifications and more; all to tailor the barrel to different projectile sizes. The standard barrel length is 600mm.  700mm Smooth Twist X-Barrel with Superior Liner With the FX 700mm Smooth Twist X barrel, comes an exciting upgrade from the standard X Barrel. It is 100mm longer and provides higher accuracy due to its more efficient air consumption and stabilizing power imparted by the length of the barrel (available in both .25 and .30 caliber). The 700mm barrel can also be utilized to extract more power from the Impact for those using it in a hunting application. You can expect to gain up to 10% more muzzle energy from the barrel when tuned properly over the shorter standard 600mm X barrel. Much like the standard FX Smooth Twist X Barrel, the 700mm barrel is housed in the FX Interchangeable liner system which allows additional barrel liners of varying twist rates and other specifications to be exchanged for different projectiles. For those who wants to experience more power from their FX Impact or who are looking for an extra edge in their competitive shooting, we highly recommend the upgrade to the unrivaled FX 700mm Smooth Twist X Barrel.
