its an automatic vl orion. All right its used, but it worked fine last week. so when i went out to test it this week i cocked it and put the co2 on (and you know how when you do it it kinda leaks out in a short spray of co2, it didnt this time? and the co2 is brand new) and when i shot it only uncocked and put the paintball in the barrel? so please dont say its a pice of crud and just but a new gun and give me an answer because i really dont know how to change the velocity or about orings and stuff
