FX STX Slug Liner
$120.99
FX STX Slug Liner
Optimized for Slugs. Fast Twist. Interchangeable Across FX Platforms.
The FX STX Slug Liner is a purpose-engineered barrel liner specifically designed for shooting heavier slugs in FX airgun platforms — featuring an optimized internal design and faster twist rate for superior stability and accuracy with slugs that require more spin to perform at their best. Interchangeable across all compatible FX STX barrel system platforms when caliber and length match.
Overview
The STX Slug Liner's faster twist rate stabilizes heavy-grain slugs that standard liners struggle to spin adequately — the .177 version excels with 10–13 grain slugs like ZAN and JSB Knockout, while the .25 version is optimized for 34–40 grain heavier slugs and hybrid slugs sized exactly at .250". Liners slip inside the main carbon fiber or steel barrel housing of your FX airgun and are extremely lightweight at just 0.25–0.5 lbs. Freely swappable between all compatible FX platforms when caliber and length match.
