FX has upgraded their STX barrel liners by creating the Superior Smooth Twist X (Superior STX) liner system. It has the same game changing exterior pressed rifling, but they've enhanced the production methods and tightened tolerances to get even more precision.
While it's about 4 inches shorter than the 700 mm 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 Slow Twist STX barrel liner to swap in now.
