STX Superior Liner FX Heavy
Direct leverbaar
As the successor to the successful FX STX Slug Liner A, the FX Superior STX Liner Heavy builds on the proven STX principle (Smooth Twist X): the rifling and lands are pressed into the liner from the outside. This creates a smooth interior and thus minimal friction. For this version, the production process has been further refined, with a few small adjustments that tighten tolerances and further increase precision.
Characteristic of this Heavy version is its different twist rate. This makes it work well with heavier pellets and slugs, resulting in high accuracy.
Working with liners has a practical advantage: within the FX STX barrel system, you can switch between calibers or twist rates without hassle. This Superior STX liner also screws in as an upgrade without requiring any changes to your FX STX barrel — handy if you want to improve your setup step by step.
