I have this spyder xtra that has been sitting in my closet for almost a year untouched cuz i got a new gun. My dad wants to start playin w/ me now so i go to get the gun and i gassed it up for him and evrything and when i would try to shoot it nothing would happen except the bolt moving foreward. The Co2 that is supposed to come out of the hole to push tha ball forward and the bolt back didnt seem to be coming out. Any answers?
