Hello all,
I've tried searching for a solution to my problem, but I can't seem to find anything to help me.
A friend of mine recently got a KWA M4A1. After a few test shots it felt as though the nozzle wasn't moving properly. After taking apart the gearbox, we got the nozzle moving but a new problem arose. After reassembling the gearbox, I found that the trigger would not pull back in Semi-auto (It would pull back in full-auto). After some more fiddling with the gearbox, we eventually got the trigger to pull back (in semi-auto) but it would lock back and not return on its own. I am thinking that this may be a problem with the gear timing. If anybody has some information it would be greatly appreciated. Thanks in advance.
Edit: So I just had a touch of idiocy. I found the problem. The spring that sits underneath the trigger had fallen out I didn't notice. Thanks to everyone for their speedy responses and great info.
