Today while i was playing with my friends i was shooting and all of a sudden the gun just stoped and i couldnt get it to cock back at all. I messed with the safety the electronics took out the bolt and put it back in it just owuldnt work. So later when i went back home i tinkered around with it and finnaly got it to shoot. The problem is that i shoot it once and the bolt just stays up and i have to cock it again to shoot. I cranked up my psi today and dont know if thatd have any thing to do with it at all. Some one help me and give me some advice on what i can do.
