Carbon Fiber Liner Sleeve, tested by Ernest Rowe and myself, has now become an official FX Airguns Accessory! It is designed to fit over your STX liner, replacing the support O-rings, to provide a new level of stability, rigidity, and harmonics to your STX barrel.

We have three lengths available in four calibers:
500mm, 600mm, 700mm
.177 caliber, .22 caliber, .25 caliber, .30 caliber
In order to compensate for the room of the liner lock and barrel attachment, each sleeve is approximately 110mm shorter than the liner.
The 500mm version is ~380mm long
The 600mm version is ~490mm long
The 700mm version is ~590mm long
Please note, this product is NOT compatible with SuperLight Barrel kits, such as the newer Crown fixed shroud barrel models, and Dreamline Compact barrel models.
These fit smoothly between the outer barrel and the liner, to replace the factory O-Rings. The clearance between the sleeve and liner has allowed for bonding adhesives, such as JB Weld, to be applied so the sleeve stays in place, but is not necessary.
If you have a Superior Liner, you will have to remove the Superior tag.
If you have questions about the product, please reach out, and we will be more than happy to provide details.
