The FX Superior Smooth Twist X Heavy (Superior STX Heavy) liner system shoots heavier slugs and pellets with better accuracy than regular Superior STX liners due to its optimized twist rate.
This Superior STX Heavy liner has the same game changing exterior pressed rifling as previous STX liners, but they've enhanced the production methods and tightened tolerances to get even more precision.
While it's about 4 inches shorter than the 700mm option, you get higher velocity compared to the shorter barrels with this 600mm model. It's a quick upgrade for your FX airgun, so buy a new Superior STX Heavy barrel liner to swap in now.
