Cylinder Head Help! Won't work!

[Noodle_2000]

Hello everyone,

 

I've had some technical difficulties recently. One of which is with my CA M15. The cylinder head was damaged some how. So I decided to replace it. I purchased a Systema V2 Steel Cylinder head. Now the gun isn't even getting 15 feet. Can anyone help me out? Possibly there is something that I didn't install correctly. If someone could guide me through so I can check, that would be helpful. Or tell me what I did wrong .

 

Thanks guys,

You've fully turned the hop-up off? Try that first

 

Best way to test if the piston has no compression: take the gearbox apart, get the cylinder, cylinder head (remove nozzle from tappet plate), stick the piston in (no spring). Jam a finger over the nozzle on the cylinder head, hold the cylinder in place and push the piston down into it - you should feel the air pressure build up

 

 

edit:

 

does the gearbox have one of those cut-out holes on the side? It's possible you got the cylinder installed backwards and the cut-out hole is too far forward, though I think you'd get more than 15 feet range from that

Thanks a bunch Catman, I'll try that when I have time.

Chances are you haven't put the feed nozzle correctly into the tappet plate. It should sit in a groove.
