No barrel "O" rings - use the ones from your existing barrel.

The new FX Airguns Superior Smooth Twist X Barrel Liner. Produced in the FX patented way; by pressing the rifling into the barrel from the outside. But now with a higher level of precision, lower tolerances and more tweaks, resulting in a superior liner. There are two types of liners being released for most calibres; a standard Superior STX Liner and a Superior STX Heavy Liner. The standard FX Superior STX Liner can shoot a standard weight pellet and Hybrid Slugs, maximising the accuracy of the FX Hybrid Slug. The FX Superior STX Heavy Liner will be replacing the STX Slug A liners in the coming months. Heavy denotes that this liner has a different twist rate better suited for heavier pellets and heavier slugs (as opposed to lighter weight Hybrid Slugs).


Only sold as separate accessory (not as barrel kit). Has a different twist rate better suited for heavier pellets and heavier slugs (as oppposed to lighter Hybrid Slugs and some manufacturers lightweight slugs).

This will require home fitting, and will need the existing barrel and liner to be removed. Airgun 101 accepts no responsibility for any damage or injury to any person or belonging when fitting or using this product. Installed at customers own risk. We do not provide a fitting service.

We DO NOT send this in ANY WAY outside the UK.
