Well suited for builds operating at field velocity limits.\u003c\/p\u003e\n\n\u003ch4\u003eGold – Low Flow\u003c\/h4\u003e\n\u003cp\u003eThe optional Gold valve expands the F2's™ tuning capabilities further. Swapping the standard Red poppet for the Low Flow Gold poppet shifts the velocity adjustment window down, letting the system run at a higher pressure while retaining lower velocity. This is especially useful for longer-barreled rifles that need a lower velocity than the F2's™ normal pressure range allows, or to maintain reliable feeding with the heavy spring and heavy BBs without exceeding the velocity limit.\u003c\/p\u003e\n\u003cp\u003ePerformance was benchmarked across a range of pressures and BB weights using a 6.05×380mm barrel.\u003c\/p\u003e","brand":"PolarStar","offers":[{"title":"Red – Standard","offer_id":45868781043746,"sku":"10000289","price":17.0,"currency_code":"USD","in_stock":true},{"title":"Gold – Low Flow","offer_id":45868781076514,"sku":"10000361","price":17.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/5355\/8050\/files\/ChatGPT_Image_Jun_30_2026_12_43_59_PM_8.png?v=1782848702","url":"https:\/\/www.katechairsoft.com\/products\/polarstar-f2-poppet","provider":"KA Tech Airsoft ","version":"1.0","type":"link"}
