Redline AirStock Gen2 Air System Kit for PolarStar Fusion Engines / HPA Systems

"I LOVE THIS HPA STOCK!

As this was my first HPA stock for my First Redline Milsim Engine, I never had to worry about the problems of a line. But later down the line I bought another Redline Engine. The Lighting. The line has snagged on a tree branch And I thought about getting another stock at that very moment XD

(pros) Very Quiet.
Decent amount of rounds before tank runs out. 1000 was my best for my DMR setup.
Easy install.
7 years later no problems with mine. So it's very reliable!

(Cons) Once the line is cut (its will be to short to redo) you better have the gearbox line setup right. Adding a tank will cause the line to move out of the spot where the line meets the stock. So the line must be all the way to the lower half of the gearbox before you use the white ring to measure where to cut the line.
You will have to cut the top back half of the gearbox off to fit the stock as the Black ring they give will pull the gearbox out of Alinement. Just follow given Instructions, Use a metal cutting blade on a hacksaw or a dremel tool and you will do fine. The gearbox is now forever only for that HPA stock.
You will be needing at least two tanks if running longer games.
The right tanks aren't cheap and in most cases The Hydro test that all tanks need every two years will cost the About half the cost of a new tank for this stock. :(
Easy to lose the Allen key for it.

I hope this helps people!
