    FX Harmonic Adjustable Barrel Tuner Shroud 500mm STD Impact M3 Sub 12 Ft Lbs For the Standard Impact M3 Sub 12 with an overall barrel length of 500MM This will NOT fit the Maverick / Compact versions of Maverick Or Impact The one accessory that will have the biggest impact on the air gunning industry is the new FX Integrated Harmonic Barrel Tuner. This integrated shroud system offers new features that will change your tuning process and give you a level of precision control never before available to an airgun. The FX Integrated Harmonic Barrel Tuner offers both dampening and tuning features that will have you obtaining new heights of accuracy from your FX Airgun. FX Airguns teamed up with Chris Turek of Up North Air gunner to bring this exciting technology to an FX Airgun. The science behind barrel harmonics and internal ballistics has been debated and analysed for years. Though there are still unknowns, what is known is that barrel harmonics exist in all guns from a .177 break barrel airgun all the way up to a .50 cal Barret. These barrel harmonics are observable and are now adjustable for repeatability. This is the art of barrel tuning. The shroud of the Harmonic Barrel Tuner first works to dampen the barrel, making the harmonic signature of the barrel quieter, more subdued, and controllable. This, when combined with the new FX Carbon Fiber Liner Sleeve ( not included ) , also stiffen the barrel system which further lowers the barrel’s harmonic amplitude (or whip) throughout the entire shot cycle. Both of these factors combined create tighter shot groups, but are only part of the overall barrel tuning that the 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. The beauty and genius of the FX Integrated Harmonic Barrel Tuner is realized with the single variable testing and tuning found both with the shroud system and internally with the new FX Impact M3. This intersection of beauty (form) and precision (function) will change the sport of precision airguns to the next level. This is a home install item. You will need to remove the existing shroud to install this item in place. We do not offer any install service. Any damage to your rifle, or any injury to any person through using or installing this product is not the responsibility of Airgun 101 Shop or its parent company. Safety first when working on any rifle, ensure the gun is safe before starting any form of work.

    In stock

    FX Airguns Angled Manometer Bracket Impact M3 For Sub 12ft Lbs and FAC / High Power M3 Impacts Only The FX Impact M3 has extra expansion holes on the right hand side just above the grip, these are to add the much requested quick view option of the regulator pressure for the rear regulator via a side mounted gauge. This kit is the bracket and O ring parts only. FX Official Kit. It does NOT include any gauges or tools for the install. Please watch the video below from Airbuks that provides simple instructions on how to add the bracket. Remember - safety first - and you are working with high pressure air so caution. When the video shows the rifle being cleared of air via adjustment of the regulator, you can dry fire the rifle a few times to bleed the system. Always check the rifle is not loaded in any way before dry firing. The rear underside regulator gauge should unscrew by hand with no air in the system. Then simply screw in the supplied blocking screw and use the rear gauge on the newly installed bracket. The gauges will not always line up horizontal this is a trial and error part of the install. Gauges may also require a bit more that finger tight to make the seal. Always use caution and select the correct tool so no damage is caused to any gauges. Basically what we are saying is - if you mess up your rifle or any parts when installing this, its down the customer - we are not responsible. But it is easy to fit. Any lost or damaged O rings during install will NOT be replaced by Airgun 101 Shop - the kits are checked before despatch and we do not carry spares. This is a HOME INSTALL kit.

    FX Pocket Wireless Chronograph V2 / MK3  Bluetooth RECHARGEABLE - SMALLER - PICATINNY AND BARREL MOUNTS You still need to connect to a mobile device or the FX Chrono Screen to get readings. IMPORTANT - .177 SHOOTERS - FOR BEST RESULTS PLACE THE CHRONOGRAPH    2 INCHES / 51MM FROM THE MUZZLE. The placement from promotional photos of the chronograph on the scope or a distance from the muzzle does not work in .177. We are NOT responsible for supplying any further instructions other than what FX includes - it is what it is instruction wise. Got to be honest, the new cardboard boxes for the Chronographs are not durable. Customer feedback on the packaging is not wrong...so please don't blame us for the tatty boxes. Airgunners want to know the velocity and power coming out of their rifle. This is especially important with FX Airguns that allow the ability to tune, change calibres, and change barrel liners. A chronograph is a key tool needed to maximize the accuracy of your rifle. In the chronograph world, you really only have two options: The expensive complicated units that give you most of what you need, but cost far too much, or the cheaper models that are outdated, not very portable, are light-sensitive/dependent, and often break easily. FX is always looking for ways to revolutionize and improve their customers experience, and they decided to find a way to offer the best of both worlds, a chronograph of high quality that is surprisingly affordable. Introducing the new FX Pocket Chronograph v2; a wireless radar chronograph that is both portable and packed with features. The Pocket Chronograph communicates via Bluetooth to your smartphone. The app (available for both iOS and Android) will show you the feet per second your gun is at, it will store an exportable shot string, and even list the muzzle energy of your rifle (in either foot-pounds or joules). Users can store profiles for different rifles, calibres, and pellets so you can easily use the Pocket Chronograph for all your airgunning needs. Future updates to the app are expected so that the versatility of the app can grow and expand. Keep in the mind the Pocket Chronograph is not just for high powered airgun use. Any projectile travelling under 1250 FPS can accurately be tracked. The Pocket Chronograph is perfect for archery, CO2 rifle and pistols, airsoft, slingshot, paintball and more. Since the FX Pocket Chronograph uses radar technology, it will work in any weather conditions, even in the middle of the night. Unlike other chronographs, no external light sources are needed! Simply place the chronograph below the muzzle, Open the FX radar app on your phone, and start firing away as the phone lists (or even calls out) your shot-string. Youll happily scrap your old chronograph and easily place this chronograph in your gun case, or just literally slip it into your pocket!

    FX Harmonic Adjustable Barrel Tuner Shroud The FX Integrated Harmonic Barrel Tuner will be offered in 600mm, 700mm & 800mm shroud lengths for both the Impact M3 as well as the FX Maverick. The one accessory that will have the biggest impact on the air gunning industry is the new FX Integrated Harmonic Barrel Tuner. This integrated shroud system offers new features that will change your tuning process and give you a level of precision control never before available to an airgun. The FX Integrated Harmonic Barrel Tuner offers both dampening and tuning features that will have you obtaining new heights of accuracy from your FX Airgun. FX Airguns teamed up with Chris Turek of Up North Air gunner to bring this exciting technology to an FX Airgun. The science behind barrel harmonics and internal ballistics has been debated and analysed for years. Though there are still unknowns, what is known is that barrel harmonics exist in all guns from a .177 break barrel airgun all the way up to a .50 cal Barret. These barrel harmonics are observable and are now adjustable for repeatability. This is the art of barrel tuning. The shroud of the Harmonic Barrel Tuner first works to dampen the barrel, making the harmonic signature of the barrel quieter, more subdued, and controllable. This, when combined with the new FX Carbon Fiber Liner Sleeve ( not included ) , also stiffen the barrel system which further lowers the barrel’s harmonic amplitude (or whip) throughout the entire shot cycle. Both of these factors combined create tighter shot groups, but are only part of the overall barrel tuning that the 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. The beauty and genius of the FX Integrated Harmonic Barrel Tuner is realized with the single variable testing and tuning found both with the shroud system and internally with the new FX Impact M3. This intersection of beauty (form) and precision (function) will change the sport of precision airguns to the next level. The FX Integrated Harmonic Barrel Tuner will be offered in 600mm, 700mm & 800mm shroud lengths for both the Impact M3 as well as the FX Maverick. COMING SOON....Price subject to change

  • FX Airguns Carbon Fiber STX Barrel Liner

    FX Airguns FX Airguns Carbon Fiber STX Barrel Sleeve

    Out of stock

    FX Airguns Carbon Fiber STX Barrel Liner The new FX Carbon Fiber Barrel Sleeve is an effective and easy way to add rigidity and dampen the harmonic signature of any FX STX Barrel Liner, all in an effort to aid the endless quest of finding unmatched accuracy from your FX Airgun. FX Airguns worked with famed Airgun Master Ernest Rowe in developing these. Many have been familiar with Ernest’s R&D work on the sleeves as he tested tolerance, material, and fit to find the most effective accuracy aid. The result is a tailor fit carbon fiber liner that fits the FX STX Barrel Liners. The tolerances fit so well that no further adhesion or gluing is necessary to obtain the stiffness needed to aid accuracy. The Carbon Fiber liner adds rigidity to the liner inside the housing. It does NOT guarantee perfect alignment or perfect concentric. It helps to firm up the liner system.  The Carbon Liner is designed to replace the current O rings to offer more stability. These Carbon Fiber Barrel Sleeves work hand in hand with the FX Integrated Harmonic Barrel Tuner in affecting changeto the barrel harmonics from the outside in, aiding the best possible accuracy of your rifle. This exciting new accessory will be available in calibers .177, .22, .25 & .30 in the various barrel lengths offered by FXAirguns. This video below is a guide, we do not suggest any sort of glue, although we have been asked.  This requires the removal of the barrel shroud, and liner to install. We are NOT responsible in any way for any damage, scratch, any sort of issue that may result from anyone trying to fit this. It should be simple, but does require the barrel to be removed. Thus SAFETY first when working on any air rifle. Check its not loaded, cocked and cannot harm you in any way. This is a home fitting item and we provide no fitting service. The Carbon Sleeve arrives as a sleeve only with no fitting instructions.  You must have a current STX liner system, this will not work with the smooth twist system.
