I test fired my a5 with e trigger for the first time and as soon as it started going full auto (9 bps) the firth ball chopped inside the barrel. Potential causes of that would be? -bad paint (but what are the odds that the fifth ball I shoot turns out to be bad paint, out of a 2 week old box) the brand I used is Toxic. -High velocity, I have not been chrono'd since I play at my friends property, not at a the field. But I don't see how at 9 bps it should really matter, I only unscrewed my velocity screw maybe 2 revolutions counter-clockwise from factory level. -cyclone feeder? shouldn't be the problem since it fed the ball and the ball broke in the barrel -Barrel? using a J&J ceramic barrel, 2 weeks old - the gun and e trigger are both 2 weeks old -Was running a 72/3000 HPA tank, the gauge read 1900 PSI at the time of the chop Anyone else got any ideas, suggestions? |

Could be the bad paint. What kind were you using? Also as far as Chrono goes 2 revs out could put it up a bit if it started at factory level. Mine was already shooting hot when I first bought my A5. ------------- Stay low, run fast, and hope that paintball doesn't hit your... http://www.deltasquad.info/">

Well, if the paint broke in the barrel and didn't break in the breech of the marker, then it wasn't a chop and can be attributed to either too high a velocity, bad paint, a burr in the barrel, or weather.
How cold was it where you were shooting? ------------- <Removed overly wide sig. Tsk, you know better.> |

around 70 F I'm assuming it was bad paint. It sucks cuz my neighbors complained while I was cleaning the chop so now I can't fix this problem till I go play. |

clean it out inside. Dont put paint in it lol. Clean the barrel out well and wait till you get some diff paint then try it. I recommend 3 or 4 am. Neighbors like that alot...lol. But seriously even in the basement you could. Just dont do it in the bathroom. Its not pretty. ------------- Stay low, run fast, and hope that paintball doesn't hit your... http://www.deltasquad.info/">
