Polarstar Fusion Engine Gen.3 Drop in Kit - V2 M4

This 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.

PolarStar Airsoft V2 Gen3 Fusion Engine:

• User-selectable Semi/Full Auto, Semi Auto Only, and Variable Burst modes.
• Open Bolt and Closed Bolt firing modes.
• Independently adjustable velocity and cyclic rate.
• Instant trigger response. Faster than an AEG with a Li-po battery

Compatible with:

• Any V2 lower receiver system
• Monk Receiver sets
• AirTac CRBN Uppers, with drop-in fitment

All kits come with an FCU, Switchboard, Wire Harness and any additional components needed to convert the specific airsoft rifle model for which the kit is configured.
