So my vulcan has been having trouble with jamming since the beginning...and from the looks of it, I'm not the only one with those issues. However, it has started to get at me a bit more, considering I'm in a local nerf tourney, and need to have a working gun for shootouts all the time.


So, I was noticing that the gun jams up when the belt feeds through, and the chain gets caught on the edge of the part it is supposed to lift over. Would this be the source of my problems? Here is where I think the problem is...





Would sanding those down to flat parts do the trick, or would that be a bad idea?


Also, just including these if they would be of any help...my current mods are:

-removing pegs from the chains
-replacing battery pack with 1x 9.6V RC Battery.



Any help would be great!
Thanks!
