  1. So my job is installing high pressure air systems for paintball and airsoft sites and everything Tommikka has said is bang on! 

    There's not much I can add to this other than my advice which would be get yourself a 300bar 12ltr tank and fill from that, your'll get more fills for your money than a 232bar and it will last forever unlike these cheap compressors from China!  As a surface use mobile cylinder it's going to need a hydro test every 5 years which is going to cost you around £50 well looked after tanks rarely fail, as Tommikka said never leave them empty and NEVER leave the valve open. 

    Get yourself a decent filling whip with a gauge if your worried about over filling as the small gauges on the bottles are rarely accurate, 3000psi working pressure bottles are tested to roughly 4496psi plus as stated you have a high pressure burst disc so it's not going to explode.

     

    Lastly and it's been said already never ever get oil anywhere near the fill nipple, I'm an ex-paintballer and was at both the events Tommikka mentioned, one was in a Millennium event in Germany and the Southampton event was a friend of mine, I was standing about 10 meters away when it happened and lost my hearing in one ear for nearly a week, the guy had to have his playing jersey surgically removed from his skin as it had fussed itself to him, he's lucky to be alive.  

    Ironically the team he played for was called '2 Hot for U'

    A hop rubber that is slightly too long can also cause this. Can you see the lips of the hop rubber through the bb feed tube? Generally you will be able to see them but only just. (<1mm). Th bb drop test can show iff bbs are getting caught (i.e. with the hop and barrel out of the gun drop a bb into the infeed tube and it should drop straight out the back without any resistance.

     

    Otherwise it might be a nozzle length issue as suspected. When you say you measured the nozzle what length did you measure and what length did you buy to replace it? Did you notice if there was a delay chip on the gear when you replaced the nozzle. 

     

    Hop rubber seems ok when tested as you described.

     

    The old plastic air nozzle was fairly beaten up so I had to try and reconstruct it, best I could see it came out at 20.53mm with my digital caliper, I went for a 20.5mm replacement so if anything slightly shorter.

     

    There wasn't a delay installed but that might be a good shout, I'll try a new tappet plate first as I have one somewhere.

     

    Thanks for the help guys, I'll let you know how I get on.

    Couple of questions - did you change anything else and when you say "misfire" I assume you mean no BB rather than more than one BB at a time?

     

    If the nozzle is too long then yes, you would have feeding issues.

    I changed the cylinder as well and the hop rubber

    Yes I mean no BB so every 5 shots maybe 3 come out but definitely not double feeding. 

     

  4. Hi, So I was given an SRC M4, I realised the tip of the air nozzle was broken so did my best to measure the length and ordered an alloy replacement.

    It now miss fires a fair amount and even more so on full auto.

    I'm guessing this is due to the nozzle being too long? Any help would be appreciated

    How long is your old outer barrel? Subtract the length of your new one from that, take the difference off the length of your original inner barrel and bob's your uncle.

    Why the hell didn't I think of that! 

    Thanks mate
