FX Impact Barrel Extension 100mm

Looking to upgrade from a 500mm FX Impact barrel liner to a 600mm, or 600mm to a 700mm, this is exactly what you need.

Scenario 1:
Remove the 1/2x20 UNF end cap from your factory barrel.
Notes with regards to FX Carbon Fiber Sleeve: If you intend you use a CF sleeve between the liner and the barrel, make sure the length matches the existing barrel (500mm) and not to the length of the upgrade to 600mm.
Install the 600mm liner into your shorter 500mm barrel.
Screw on the FX Impact Barrel Extension (100mm).
Finally attach the 1/2x20 UNF end cap from your factory barrel you had removed earlier.
You are done with the installation.
