WE G39c semi not working

[Auto_Demon]

so i was firing some shots with my gun on semi auto today and it kept firing 2 and 3 round bursts and rarely 1 shot, some times it shot about 5-7 shots at once. anyone know what the problem might be? it seem like there is a problem one after the other with this gun, any help would be greatly appreciated

Damn, 2 threads in the last month, please don't tell me "I didn't find anything by searching by myself."

Did you do any upgrades before the rifle starting going burst? Or is it stock? Is it new, or has it been used heavily?

If I had to guess, I'd say the sear is either wearing out or not resetting. But that would be dependent on how old the rifle is and how heavily it's been used.

Check audi_bhoy's first link - has a teardown video link further down the thread.

rather then make another topic about the g39 ill post here...

I also have a problem with my Semi but mine is the lack of semi all together.

Installed full RA-tech parts and now the Hammer locks on semi, everything seems lined up, full auto works perfectly even full mag dump. I'm kinda lost at this point every post I find about g39 and Ra-tech problems is full auto not working. Maybe ill strip it down for a 5th time and try again.

edit* someone talks about the same problem I have on another post but it was never resolved.

His problem is that the gun doesn't even shoot in semi-auto AT ALL.
When you cock the lever it doesn't engage the hammer properly, when you switch it back to safe, then it locks the hammer in the right position. It fires once and then doesn't lock back properly again.

If it's firing on FA but not SA, then you likely reassembled the trigger pack incorrectly. The most likely cause is springs not installed correctly (backwards or not properly tensioned).

See 2nd post in this thread, click on first link and scroll down until you see another link to a youtube video. That video provides a comprehensive teardown of the trigger pack. Obviously, reassembly is in strict reverse order. The video will help you reassembly correctly, and have you shooting SA & FA afterwards.

This is the same video that I used to teardown and upgrade my G39C trigger pack. My rifle shot SA & FA reliably afterwards. As far as I can tell, this is one of the very few G39 trigger pack teardown videos out there that's actually useful.
