Hi folks, yesterday during an event my Daughters MP7 seems to have developed a problem where it can only fire 2-3 meters (luckily happened in the last game of the day) I doubt its related but I had just changed the battery right before the match, but was still running the same type of 7.4v just the one out of my UMP.
the MP7 still fires & there is no unusual noise or anything (no grinding from the gearbox) the gels only travel about 1-2 meters though, I was thinking maybe the return spring has snapped ? i cannot hear anything rattling around loose though. Got home quite late so I have not tried pulling it apart yet.
Any other theories on what might be wrong ?
