Hey guys, sorry for more noob questions, but I'm having a problem with my stampede. I did a spring upgrade/AR removal (nite finder spring), I put everything back where it should be according to a tutorial, and I'm sure I did everything right except ONE thing. Where you put the bolt sled back in, theres a small orange piece of plastic sticking out of one of the gear wheels, and I'm not sure if that's placed correctly in line with the bolt sled. Anyway, now when I close it up and try to fire it, the bolt sled goes forward and then instead of firing and going back, it makes gear-grinding sounds over and over again and won't fire. I have to open it up again to de-prime it. I've adjusted that piece of plastic by the gear MANY times and I get the same result. Any ideas?
TL,DR: Stampede is stuck primed and it may be a gear problem. What did I do wrong?

I know I'm an extreme noob for posting this but I can't rack my brain for the answer. I recently AR and spring modded my Longshot. This is my fourth, and this has happened before, but I can't remember what I did to fix it. When I close it up and try to cock it, it gets about a centimeter away and then stops. I can't get it back any further. Yes, I reinforced the catch, so that's not it. Could someone please tell me what the hell I'm doing wrong?
