This FX Superior Smooth Twist X Heavy Barrel Liner or Superior STX Heavy Barrel Liner is a replacement for the original FX liner and is specially developed for the use of slugs.
They are created using the same patented innovative exterior-pressed rifling, but using upgraded techniques and tighter tolerances for greater precision.
The Superior STX Heavy will shoot slugs with improved accuracy over the regular STX barrel liners.

Superior Heavy Liner Twist Rates

Sold as a separate accessory and not as a barrel kit.
 
Has a different twist rate better suited for heavier pellets and heavier slugs (as opposed to lighter Hybrid Slugs and some manufacturer’s lightweight slugs).
