Well I researched this on this site and with google. Cannot find any appropriate info so I am hoping one of the other gundocs on here may have solved this problem.

I have many lower receivers, 2 are G&G. One is a metal lower and the other is a Cansoft clear lower (painted black). When I put a gearbox in a G&G lower the selector switch seems to work well but the three positions produce - safe, semi, semi , with no full auto.

This happens only with the two G&G lowers. I have Magpul and genuine TM lowers and the same gearboxes will select - safe, semi, auto on those lower receivers.

Can anyone tell me why G&G receivers in particular have this problem? and how to solve it?

Thanks for any help you can offer.
