In the picture you can see the cap for the spark sticking out and if you look at pictures of the tpx on the tippmann site you can see the barrel sticks out further and i honistly didnt realise it was missing until you said. i simply got the marker put 3 mags through it on a field, took pictures and put it up as i seen it its only when i checked the parts list ( which i can email you if you like) that i realised that the barrel was missing but as i said i spoke to bz paintball on friday and dameo is getting me prices also i need to know what o-ring is blown pref i need a part number
