1)Piston Head O-ring
Common cause: Worn out or sometimes even new ones shrunk in time or incorrect size (Bore up or non bore up)
Suggestion: Replace
2) Cylinder Head O-ring
Common cause: Worn out, sometimes shrunk in time or incorrect size (Bore up or non bore up)
Suggestion: Change Oring or wrap a few layers of teflon tape until its tight enough with the cylinder, Or replace with double o-ring type Cylinder head
3)Nozzle
Common cause - Worn out nozzle or incorrect nozzle size. I think nozzle size varies with the type of gun so its not a one size fits all. In adddition there are Bore up and non bore up type of nozzle.
Note: Nozzle slides with the Cylinder head nozzle, you cant make it too tight otherwise nozzle woulndt slide at all so they are bound to have leaks, but the key is to minimize it.
Suggestion: Replace with an air sealed nozzle or the one with O-ring type (havent seen one though).
4)Mating of Hop rubber and nozzle
Common cause: Worn Hop rubber (lips torn) and/or worn nozzle tip, incorrect nozzle length or size
Suggstion: Replace
5)Fit between Hop rubber and Inner barrel
Common cause: At certain pressure the hop up rubber tends to balloon out from the air pressure thats chaneling from the small opening of the inner barrel (where the small hop rubber goes in).
Suggestion: To prevent this, after inserting the inner barrel to the hop up rubber wrap a few layer of teflon outside the hop rubber so it will hug the inner barrel more but thin enough so it will still go in to the hop up chamber.
If you have any correction or addition please feel free to share.
