so i went to the woods today and took some practice shots and after 30 shots it started double firing, and after 100 shots it went full auto and wudnt stop till i took out the co2 tank out. i only installed the tech t fang trigger and replaced springs for the seer and the trigger so i could do the pen spring mod. the bolt and the seer is not worn down because i just bought it 2 months ago and it didnt even go through a case yet. and i have took the whole thing apart and put it back together. is there something im doing wrong if so tell me.
