guns been working fine at home and in garage but when i got to the paintball site was going funny wasn't shooting as it should few shots then the sound changed in the gun could tell it wasn't shooting properly and was the reason balls wasn't getting shot correctly. i got home tested my bottle and hyper 3 reg with my uncles bottle and reg and was still doing it, changed battery and still doing it, cleaned eyes and re lubed the bolt still doing it. If i look down the feed neck even when i turn the eyes off with no balls i can hear and see whats going it the 1st shot is ok then the other shots do no make as load a noise and i can see that the bolt isn't going as it should be but i have lubed the bolt and changed the GREEN, YELLOW on outer bolt and the two RED and one BLUE on the inner bolt but its still doing it. only thing i can think of is the board but i can still configure and set the gun up as normal so, maybe there is something stuck in the airport , iv no idea. any help would be good.
