Dual solenoids allow for the nozzle and the poppet valve to be adjusted independently of each other for unparalleled control over both the loading time and air volume used. Additionally, this makes it possible to change the firing sequence giving it the ability to operate in both true closed bolt as well as \"AEG\" mode.\u003cbr\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/7466\/4301\/files\/FEV2_Description_1.jpg?v=1553525647\" alt=\"\"\u003e\u003cbr\u003eThe F2™ incorporates a new one-piece, lightweight poppet valve design yet still operates on the same principle as the Fusion Engine™ poppet. This valve is able to operate at lower pressures and uses less air volume to function which optimizes air efficiency.\u003cbr\u003e\u003cbr\u003eA robust design allows for an operating pressure range of 45psi to 145psi which enables the F2™ to achieve velocities from CQB to DMR while employing only one nozzle for the entire velocity adjustment range.\u003cbr\u003e\u003cbr\u003eAdditionally, its nozzle is spring biased forward which provides a consistent loading force regardless of operating pressure. It shares the same spring as the Fusion Engine™ with both light and heavy spring options available to adjust the loading force.\u003cbr\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/7466\/4301\/files\/f2-cutaway_1200x500.jpg?v=1553527045\" alt=\"\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGel Blaster Compatible\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eF2 HPA conversion kits are specifically configured for use in Gel Blasters only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cimg alt=\"Gel Blaster F2\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/7466\/4301\/files\/F2_Gel.jpg?v=1631808469\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e \u003cem\u003e**All kits come with an Engine, FCU, Switchboard and Wiring Harness MCU\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThe HPA Tank, Air Setup (regulator\/line\/QD fitting) and Battery needed to operate the system are purchased separately.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003c\/h2\u003e","brand":"Polarstar","offers":[{"title":"Default Title","offer_id":48291555508438,"sku":"95030000002","price":980.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0084\/8297\/9945\/files\/Screenshot_2026-05-26_144908.png?v=1779773777","url":"https:\/\/m4a1gelblaster.com\/products\/jack%e2%84%a2-hpa-conversion-kit-copy-1","provider":"M4A1 Gelblaster","version":"1.0","type":"link"}
