my friend just bought a diablo mongoose and when you shoot it u can get like 3 balls off than the bolt doesnt recock so he is gettin mad and startin to not like paintball anymore so when he went to work i took a look at it and i figured it had somthing to do with the CO2 so i took the bottom line kit off and hooked the tank directly to the gun and it shot fine i checked the washers and o-rings & they were all good. Any ideas
