We M92F going fully automatic
 

My we m92f is shooting fully auto now and it never used to I have looked everywhere on the Internet to find what the problem is and I've had the gun apart several times and apart from some wear on moving parts nothing is broken or missing. If someone has any advice it would be much appreciated.

There is your problem.

WE does not makes bad guns, they just use crappy stuff to make them.
That is why they break or wear down way too fast.

I would suspect the slide-return sear/lock to be too worn to be pushed in by the slide going back. So when it comes back forward, the hammer follows and fires again.

What Kos-Mos said. Older WE models such as their berreta, hicappas and 1911s tend to have a short usage life.

How many times would you guess you have fired it?

Probably 8000 rounds maybe more
