KJW M4 GBBR Trigger Not Re-Setting

Saberwing · January 12th, 2011, 16:16

So I have a KJW M4, and when I fire it on semi, the trigger doesn't reset, and I physically have to push it forward to fire the next shot. This does not happen when firing full auto though.

Any ideas as to why this could be happening?

I recently had the same problem on my metal lower. I sprayed it with some sili oil, and just ran through the motions until it ran smooth. Havent had the issue come back. Also, check for a small piece of debris near the trigger/ fire selector.. Thats the extent of my experience

have you changed anything on it?

if springs come out of place they have to be replaced properly...

(Damn.. I knew I should have made that video on how to take one apart and put it back together when I had the chance!!)

Amos make the video! No one has for some reason. The internet needs one.

I'm having the same problem, silicone oil didn't help, I'm scared to open it up because I can't find any disassembly guides. Anybody??

Id make the video as I am very familiar with KJ M4 after owning one for 2 years, but am moving on Monday and will not have time. Maybe in a month or so if Amos doesn't beat me to it : p
