WTF, KJW M9 shooting full auto?
 

Any idea why would a KJW M9 keep shooting on full auto?
The mag doesn't have any BBs in it, and the slide doesn't go all the way back. It does lock on empty if I manually pull the slide.

Your trigger bar is probably worn or something. This is actually something people try to do, it's the full-auto mod where they file down the trigger bar.

You can use http://shop.ehobbyasia.com/guarder-s...92f-black.html to replace it I think.

Your trigger bar may be worn or sticking..

Maybe you should trade your spare trigger bar with him so you can get full auto since your own attempt failed. :p

If he *Needs* it,... For sure..

Yep, I highly prefer semi auto!

If it's the case, what area of the bar would be worn so I can check that?

The problem would be if your trigger bar broke, Heres a video on how to do an actual full auto mod that would also explain how the trigger bar catches the slide.

you revived a 4 year old thread for a simple solution that was solved?

Seeing as it is his first post and given his name... I deduce that he is trolling you good sir!
