PolarStar Airsoft PR-15 V2 Gen3 Fusion Engine Electro-Pneumatic Gearbox Kit
by Rene P. Date Added: December 29, 2011
Polar guys are awesome.

I can honestly say that installing this in around 10 minutes was the best decision I ever made. Only thing is if you are using a 650 mm barrel and you are trying to stay below 400fps you will have to use it on a much smaller air intake. Which is easy.

I must say that this thing can kick my buddies systema's booty pretty easy.

There are many guides on it and many testing videos on it so you can know what to do.
