PolarStar Airsoft M4/M16 Generation 3 Version 2 Fusion Engine
The PolarStar Fusion Engine is the perfect HPA compatible engine for optimal customization. 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.
