Liner tube extender adds 100mm or 10cm, this extender is designed and manufactured from the same material as the official FX tube.
Recommended to extend a barrel tube to increase its length, you would need to get a longer liner as well.
Both are threaded, male - female. External diameter is the same as the original tube.
Example: 600mm barrel + extender + 700mm liner -> 700mm barrel.
