Well, I have run across this issue with a few guns. Maybe someone could enlighten me on what the problem is.

I just reassembled a KWA M16 for a customer (the safety switch was broken). The gun used to feed perfectly, now it won't feed unless I remove the mag and hold it upside down. Then it will feed the 4 or 5 bbs in the hopup. With the mag inserted it will fire one bb then nothing, even upside down. I must flip the gun upside down and remove the mag for it to feed at all.

I also had a JG M4 doing the same thing and I never figured out what it was.

Any ideas?


EDIT: In the interest of saving many posts here is some information:

1) hopup is lubed
2) multiple magazines tried, including PMAGS that were used in this gun all of last year
3) I took the hopup apart and reassembled it
4) I removed the gearbox and lower hopup from the receiver, then reassembled it
5) This gun was feeding right up until I reassembled it after the above mentioned servicing
