Our Take

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.

    I love the pro gunbuilder by golden eagle!
    The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
