This engine offers upgradable parts that other engines don't offer. These nozzles have different boar sizes that effects your air efficiency and can ultimately benefit from this. Featuring a Fire Control Unit (FCU) that is very user friendly, you can adjust your settings from rate of fire (ROF) to trigger pull and make it significantly faster and more responsive than users with AEGs. The fusion engine comes in different gearbox shells fitting V2 and V3 to LMG gearboxes. Why worry about damaging your AEG's internals because of which battery it can handle? This fusion engine uses a 7.4 LiPo battery and does not inflict harmful damage to your rifle's internals. It can offer so much and perform higher than your standards anticipated.\u003c\/p\u003e\u003cp\u003eIn the Box\u003cbr\u003e1X Fusion Engine\u003cbr\u003e1X FCU\u003cbr\u003e1X Set of Wireharness'\u003cbr\u003e1X Trigger board\u003cbr\u003e1X Manual\u003cbr\u003e\u003cbr\u003eSpecifications:\u003cbr\u003eBrand: Polarstar\u003cbr\u003eNozzle Type: SR25 GG\u003cbr\u003eCompatibility: SR25 GG\u003cbr\u003ePropellant: HPA\u003cbr\u003eMaterial: Aluminum Alloy\u003cbr\u003eColor: BLACK\u003cbr\u003e\u003cbr\u003eCalifornia Proposition 65 Warning: Cancer and Reproductive Harm - www.P65Warnings.ca.gov\u003c\/p\u003e","brand":"PolarStar","offers":[{"title":"Default Title","offer_id":53883049279854,"sku":"PS-FEV2-SR25GG","price":470.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0899\/9524\/7982\/files\/pd-23115-1800x1200-1-480x480.jpg?v=1780815277","url":"https:\/\/store.xtremeairsoft.net\/products\/polarstar-hpa-fusion-engine-v2-gen-3-g-g-sr25-gearbox","provider":"XTREME Airsoft Superstore","version":"1.0","type":"link"}
