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.
FX's innovative liner system allows the internal liners to be exchanged for other types.
This STX Superior Heavy liner has a special twist rate that is well suited for heavier pellets and slugs
The ideal upgrade for the Crosman 2240, 2250, 2260 and the 1322!
In addition to an 11mm dovetail cut for optics, this steel breech also provides a firmer mount for the barrel, resulting in better precision.
Caliber .22 (5.5mm).
