Carbon Fiber Liner Sleeve

Originally tested by Ernest Rowe and myself, the carbon fiber liners are now an official FX Airguns Accessory! The Carbon Fiber Sleeve is designed to fit over your STX liner, replacing the original support O-rings. The Liner sleeve provides a new level of stability, rigidity, and harmonics to your STX barrel. Installing the sleeve is a must when you start to shooting higher power and want that next level of accuracy.

Carbon Fiber Liner Available Lengths 

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.

For example:

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.
