TM M4 won't fire.
Hey there, I just received this gun in a trade last week. The day I got it I threw a battery in and it fired no problem, I put about 300 BB's through it. I took the battery out and haven't fired it since. Today however I had decided to make a home-made suppressor and needed to test it. When I put the battery in and pulled the trigger - nothing happened. I thought "well that battery was on it's last leg anyway" So I grabbed my other 8.4v and tried it. Still nothing. The only thing I had done to the gun between the first time I fired it and today was open up the upper receiver to take a look-see, as I just acquired the gun, and play around with setting up my three-point and aimpoint.
I don't know anything on internals, and the only thing I can think of is that maybe the wires from the gearbox got pulled a bit when I tilted the upper receiver forward. (fore grip battery). But at the same time I feel like I would have felt some extra force required to pull.
I've been reading the FAQ's up and down and haven't seen anything. Any help would be greatly appreciated.
Whitey.
