WE g39c no semi
 

I have a WE G39c that had a NPAS installed, ran it for a bit then it stopped fire a few weeks ago, I noticed the firing pin was worn so when I opened it up to replace it found that the Valve Locker was snapped, now that all the parts listed have been replaced it now only fires full auto even if its set on semi.

any idea?

Sounds like the disconnector doesn't work, did you reassemble everything as it was? Try looking for missing parts, or bent parts. I don't have my WE G39 on hand right now to visualize the mechbox, unfortunately.

Check the trigger sear and see if the spring between the sear and trigger is sitting properly.

how should it be sitting?

I dont mean to be spoon fed on the subject but I searched a ton and I've been unable to find what I need.

neavermind it looks to be sitting right I think

The only other things I can think of is that the selector cross bolt or top bar weren't reinstalled correctly, or a spring is missing.

I'm not at my personal computer (at work), but will post a link to a trigger pack disassembly video this evening (same one I used to learn with - very comprehensive).

oh dude if you could post it that would be great

Trigger pack disassembly video. Reassembly in reverse. I used this to tear down, upgrade, and reassemble my trigger pack without prior knowledge. My semi and auto worked just fine afterwards. Hope it helps.
