Hi, so I bought a spyder MR1 months ago. I've only played one game on it, but I've done tons of target practice. It has worked fine until Sunday. I was shooting with a friend and it jammed. I wasn't sure what to do, so I pulled on the cocking pin until it became unstuck. Then I shoot a few times and about 10 balls came out. After that it worked fairly well but every now and then it shot 2 at a time. When I brought it in to clean up, there was a rattling sound when I shook it, after I took out all of the parts. I shook it and a black piece fell out along with a thick rubber circle. I looked it over and guessed as how it should go back in. But the piece that moves when you pull the trigger was in the way. I was able to shove the rubber thing past it, and after minutes of pushing really hard on the black metal piece, I acidently hit the trigger which moved the metal piece in. Today I decoded to try in out again. Everything worked alright, but still in about half a hopper 2 balls were shot at once, about 5 times. That's wayyy more then usual. Then a ball popped in the barrel (I use really cheap balls for target practice.) After that the gun was very inaccurate though I don't believe the problem was affecting that much. I came inside to clean it up and the black piece was rattling again. I popped it out and put it back in. It still rattles a little but not as much. Any suggestions on what to do? It's not working as well as it used to and I have a game this saturday. Thanks!
