The FX Smooth Twist X (STX) barrel system — found on the Impact, Crown, Wildcat, Dreamline and related platforms — allows the inner liner to be removed and replaced to change calibre or twist rate. The liner lock is the threaded retaining element that holds the liner firmly in place during shooting; when changing liners, the shroud is removed first, then the liner lock is unscrewed to free the liner. Using the correct calibre-specific liner lock ensures a proper mechanical engagement with the .25 liner's dimensions. This is a genuine FX Airguns factory spare and the part to order when a liner lock is lost, damaged, or required as part of a calibre-conversion kit.\u003c\/p\u003e","brand":", Export_Restrict: True , Export_Block , LS-RM Default","offers":[{"title":"Default Title","offer_id":45232910958792,"sku":"S83340","price":34.83,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0071\/8906\/9860\/files\/mR98YLUNaG5yiP0NeVC0rdu6nb31cPmX-35.jpg?v=1792056646","url":"https:\/\/www.bushwear.co.uk\/products\/fx-liner-lock-25-stx-barrel-liner-lock-for-25-calibre","provider":"BushWear","version":"1.0","type":"link"}
