FX Carbon Fiber liner sleeve

This FX Carbon Fiber Barrel Sleeve has been specially developed to stiffen the liner of any FX air rifle with an STX barrel, greatly reducing the oscillations and vibrations that occur.

As a result, the barrel moves less and it will do its job more accurately.

By using carbon fiber, the sleeve is extremely stiff, while adding hardly any weight.
The tolerances are so tight that the FX Carbon Fiber Barrel Sleeve can be mounted without glue.
