Carbon Fiber Sleeve designed and tested by Ernest Rowe to fit over your STX liner to provide a new level of stability, rigidity, and harmonics to your STX barrel.

We have three lengths available in three calibers:
500mm, 600mm, 700mm
.22 caliber, .25 caliber, .30 caliber
In order to compensate for the room of the liner lock and barrel attachment, each sleeve is 100mm shorter than the liner. For example:
The 500mm version is 400mm long
The 600mm version is 500mm long
The 700mm version is 500mm long with a separate 3.5" (~90mm) extension
** 700mm version is 3.5" (~90mm) short of covering the entire liner. A separate 3.5" (~90mm) extension is provided with each 700mm purchase. If you do not find the extension necessary, you can order the 600mm version. **
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 is allowed for bonding adhesives, such as JB Weld, to be applied so the sleeve stays in place.
