The valve stop is the component that physically limits and sets the maximum travel of the valve as it opens on each shot — by controlling how far the valve can lift, it directly influences dwell time, the volume of air released, and ultimately muzzle velocity. On the FX Impact platform, where the valve system is a central part of the rifle's adjustability and tuning range, a worn or damaged valve stop will cause erratic power output and make it difficult to hold a consistent tune. This factory replacement restores correct valve travel geometry. It is a small but critical component: without the valve stop holding its dimension precisely, the rest of the valve tune becomes unreliable. Confirm fitment against your specific FX Impact generation before ordering.\u003c\/p\u003e","brand":", Export_Restrict: True , Export_Block , LS-RM Default","offers":[{"title":"Default Title","offer_id":45144211226824,"sku":"S83307","price":14.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0071\/8906\/9860\/files\/M7bTvpK57fKfGn7BYdUEIi5fMGOiuSpe-35.jpg?v=1784358083","url":"https:\/\/www.bushwear.co.uk\/products\/fx-valvestop-impact-genuine-fx-airguns-spare","provider":"BushWear","version":"1.0","type":"link"}
