I'm trying to use my old modded Stampede for Nerf Wars at my high school next season. The problem is that it won't fire. I have checked the catch spring and hidden spring but they're both fine. I originally had four 3.7 V TrustFire AA batteries in it but they weren't doing the trick so I added four more, still nothing. I've checked my battery tray and it is set up correctly. I took out one of the two springs I had installed into the plunger tube to see if it'd help, still nothing. Everything is re-lubed. I'm not sure what is going on and I'm just trying to be kill leader again. Any suggestions or help is appreciated.
