Polarstar Fusion Engine Gen.3 Drop in Kit - V2 M4 Slide Catches trigger pin and trigger pinThis is a complete drop in system which replaces the entire AEG gearbox with a full CNC machined lightweight aluminum chassis. It is the most adjustable system we produce with the widest range of adjustment in both velocity and rate of fire. Being a dual solenoid, closed bolt system so you are able to adjust the poppet valve (firing air) and nozzle (feeding) independently for full control over both the loading time and air volume used.
