The FX Carbon Fibre STX 700mm 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 FX Carbon Fibre STX 700ml Barrel Sleeve results in a tailor fit carbon fiber liner that perfectly 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.

These Carbon Fiber Barrel Sleeves work hand in hand with the FX Integrated Harmonic Barrel Tuner in affecting change to the barrel harmonics from the outside in, aiding the best possible accuracy of your rifle.
