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.
