FX Superior STX Barrel Liner .25 Calibre 600mm Pellet & Slug
S83291
The FX Superior Smooth Twist X (STX) Barrel Liner in .25 calibre and 600mm length is the factory-standard liner for FX Impact, Wildcat, Dreamline and Crown rifles, and is sold separately for barrel kit replacements. Using FX's patented outside-in rifling process, the bore geometry is held to tighter tolerances than cut or button-rifled alternatives, giving consistent projectile engagement across the full liner length. This standard Superior variant has a 1:24 twist rate, calibrated for standard-weight .25 pellets and FX Hybrid Slugs. The .25 calibre is a strong choice for hunters targeting quarry up to rabbit and squirrel size where additional downrange energy matters, and the 600mm length provides a practical balance of velocity and handling. Supplied as the liner only; no barrel kit or fittings are included.
