{"product_id":"fx-airguns-fx-impact-tungsten-hammer-weight","title":"FX Airguns Impact Tungsten Hammer Weight – Slug Tuning","description":"\u003cp\u003eThe FX Impact Tungsten Hammer Weight is a direct-fit upgrade for the FX Impact PCP rifle, designed for shooters who want to push the platform to higher regulated pressures when running heavy slugs. Tungsten is approximately 1.7 times denser than the steel used in the standard FX hammer, so the same physical size delivers substantially more mass striking the valve pin. That extra force keeps the firing valve open for longer — a meaningful gain when driving slugs through 700 mm or 800 mm barrels, where extended valve dwell allows air to keep accelerating the projectile further down the bore. The heavier hammer is particularly suited to regulated pressures in the 155–180 bar range; at 150 bar and below it can be difficult to tune consistently, so it is not recommended for standard pellet shooting or lower-pressure builds. For Impact owners building a high-power slug setup, this tungsten hammer is the recognised starting point for the conversion.\u003c\/p\u003e","brand":", Export_Restrict: True , Export_Block , LS-RM Default","offers":[{"title":"Default Title","offer_id":42452399587528,"sku":"S83399","price":31.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0071\/8906\/9860\/products\/Ji1Hzu83KdAIvBnvswhiZ8yVeozHfKnY-24.jpg?v=1669123292","url":"https:\/\/www.bushwear.co.uk\/products\/fx-airguns-fx-impact-tungsten-hammer-weight","provider":"BushWear","version":"1.0","type":"link"}
