KJW M4 GBBR Trigger Not Re-Setting
 

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!!)

Completely stock except for the RA-Tech Piston

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

I would, but i don't have a KJW right now lol

When I get my next batch of them I will.

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
