The rifling is pressed into the liner from the outside using FX's patented process, which holds tighter tolerances than cut or button rifling and produces a bore that tracks both pellets and slugs cleanly. The 1:24 twist rate of this standard Superior variant is tuned for standard-weight .22 pellets and FX Hybrid Slugs, making it a versatile choice for hunters and field shooters. At 600mm, it offers a step up in muzzle velocity over the 500mm liner while keeping the overall rifle length manageable — a popular middle-ground length on the Impact and Crown platforms. Supplied as the liner only; no barrel kit is included.\u003c\/p\u003e","brand":", Export_Restrict: True , Export_Block , LS-RM Default","offers":[{"title":"Default Title","offer_id":42350047527112,"sku":"S83289","price":86.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0071\/8906\/9860\/products\/K5O8tbjZHbBNkFMvfGxrt81wXSFCpK8L-24.jpg?v=1664530982","url":"https:\/\/www.bushwear.co.uk\/products\/fx-airguns-fx-superior-stx-liner-22-600mm-pellet-slug-impact-wildcat-dreamline-and-crown","provider":"BushWear","version":"1.0","type":"link"}
