I just got done re-assembling my KWA M16, integrated a MOSFET trigger system into it, and then I pulled the trigger a few times and then the trigger kept getting stuck back, it wouldn't spring return, took it apart, and I found that the trigger contact block broke in half! The rarest part to every actually break, and mine broke in half, lol. How I'm not exactly sure, but it is somewhat of a wedge shape on the bottom, and its thin there, which is where it broke. Anyhow, there is an easy fix if this happens to anyone, CA glue(aka super glue). I used Loctite Super Glue ULtra Gel, its pretty good stuff, I use it for glueing tires on my E-Revo(4x4 R/C monster truck). Anyhow, I glued the seem back together where it broke, then I gobbed it up under the silver contact and let it dry, so it should be much stronger than originally with the extra glue support I made. Its a cheap and good fix for that part if anyone ever breaks it. For future reference to KWA, maybe they could make it a little thicker or different type of material? I think a little more flexible plastic, like nylon would have prevented that from happening. Hope this helps. If I recall there was a post not to long ago with the same or similar symptoms, I think that may have been the cause. Perhaps it just a fluke with recent batches as mine was bought new in Nov., I believe the two M16's were recent in that post as well.
Keep it going KWA!
BTW even the M130 spring has a ridiculous ROF with my 11.1v LiPo. They are awesome power sources.5
