PolarStar F2 M4 Player Package | HPA Drop In Kit
The PolarStar F2 is one of the most used HPA engines in the hobby today. With its dual solenoid design, the F2 provides the same functionality as the legendary Fusion Engine, but in a more compact, efficient, and flexible design. The dual solenoids allow for the nozzle and poppet valve to be adjusted independently from each other for control over both the loading time and the air volume used. It is also possible to change the firing sequence giving the engine the ability to operate in AEG and closed bolt mode. The one piece, lightweight poppet valve is able to operate at lower pressures and uses less air volume allowing the engine to optimize air efficiency. The robust design of the F2 allows for an operating pressure anywhere from 45psi to 145 psi. This means that the F2 can be utilized for any application. The F2 player package allows you to get the engine as well as all of the accessories you'd need to get up and running. 
Package Includes:
PolarStar - F2 V2 Conversion Kit (M4/M16)
Your choice of 7.4v Mini LIPO Battery, connector, or neither. Please keep in mind that all FCU come wired to JST connectors.

Great HPA engine. Probably the best available right now on the market. You can also get a cheaper version like the jack engine that is less pricy. If you wanna get into speedsoft the polarstar f2 is the best.

This bundle came with everything I needed. I dropped the f2 in my lancer tactical and it performs perfectly each time I go out to the field. Overall I think if you are trying to get a HPA engine than get this bundle it makes things a lot easier!

I recently bought a polarstar F2 and I installed it into my gun. I had to dremel out a bit of my gearbox, other than that it shoots perfect and I love it.

I just had my F2 installed in my airsoft gun and it is beyond fun to play with now. The trigger response, the rate of fire and more importantly, the consistency of shots and accuracy is ridiculous!

The polar f2 runs fine in itself. What the issue is however is the install. After installing the engine into my G&G Warthog, the gun blew air out but would not chamber a bb. after messing with settings i was only able to get a bb through with a higher psi(120psi). meaning more air being used and more fps which i cant do at the fields i play at. after messing with more i removed a spacer inside the nozzle spring which made it feed a bit more consistently. but not perfect. Not sure that this abnormality is the gun i installed it in or the f2 just needs to be loosens since the spring was very tense. all i know is i will try to further chop that nozzle spring and see if i get improvement. as for the kit, very simple and straight foward install.
