This FX Superior Smooth Twist X Barrel Liner (Superior STX Barrel Liner) was created using the same innovative exterior-pressed rifling, but using upgraded techniques and tighter tolerances for greater precision. The Superior STX will shoot both pellets and slugs with improved accuracy over the regular STX barrel liners. Shooters will see the greatest accuracy from FX's new .25 caliber Hybrid Slugs using the Superior STX barrel liner. This 700mm version gives you a little more speed than the shorter versions, making it ideal for long-range shooting. If you're looking for an easy way to upgrade your FX air rifle, get a Superior STX barrel liner and drop it in today.

FX Superior STX Liner, 700mm, .25 caliber

  • Recommended for use with diabolo pellets and .25 cal FX Hybrid Slugs
  • Compatible with 700mm barrel models of FX Crown Continuum, Impact, and Wildcat models with STX barrels
