Ok so i hooked up some CO2 to my ego 08 to test and see if it shoots only air(i know compressed air is optimal but i'm not getting my tank till later this week). The bolt will click and the gun will fire but you cant feel any air comming out the barrel and the bolt wont cock back into the ready position so its just blocking where the paintballs would feed into. So it cocks half the distance its suppose to. I relubed the bolt and the silver piece on the bolt is all the way down. Anyone know what the problem could be?
