Where standard or high-pressure gases may struggle to cycle reinforced or extended systems reliably, 4.0 delivers the maximum operating force required to maintain consistent mechanical function.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eHeavy steel bolts, long-stroke systems and upgraded internal components increase resistance throughout the firing cycle. The 4.0 blend is engineered to overcome that resistance while maintaining controlled, predictable pressure behaviour. This results in strong recoil impulse and dependable cycling even under demanding conditions.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe formulation incorporates NUPROL’s highest-pressure trace additive expansion profile to promote rapid and stable gas expansion inside the magazine. Silicone lubrication supports seals and valves against the increased mechanical load, helping maintain operational consistency during extended use. For advanced GBB rifle setups that demand uncompromising power delivery, 4.0 provides the upper tier of the NUPROL pressure range.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4.0 ultra-high-pressure performance grade\u003c\/li\u003e\n\u003cli\u003e300g full-size cylinder\u003c\/li\u003e\n\u003cli\u003eSilicone-lubricated formulation\u003c\/li\u003e\n\u003cli\u003eTrace additive expansion system\u003c\/li\u003e\n\u003cli\u003eOptimised for heavy bolt rifles and DMR platforms\u003c\/li\u003e\n\u003cli\u003eDelivers maximum recoil impulse\u003c\/li\u003e\n\u003cli\u003eStable cycling under extreme mechanical load\u003c\/li\u003e\n\u003cli\u003eEnhanced output for harsh or cold conditions\u003c\/li\u003e\n\u003cli\u003eIncrease in FPS when you let your gas settle in the mags!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWarning - Due to the power of this gas it is recommended that you do not use it with Gas Blowback Weapons with Polymer \/ Plastic Slides as it can damage or break them.\u003c\/p\u003e\n\u003cp\u003eDownload - \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1047\/1712\/3933\/files\/Nuprol_Gas_Series_Data_Sheet.pdf?v=1773174327\"\u003eNuprol Gas Series MSDS Data Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":63807434883421,"sku":null,"price":17.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1047\/1712\/3933\/files\/nuprol-4-0-300ml-1.avif?v=1773228380","url":"https:\/\/pointman-systems.com\/products\/nuprol-4-0-airsoft-black-gas","provider":"My Store","version":"1.0","type":"link"}
