CA36c full auto problems
 

I recently purchaced a Classic Army CA36c. I like the gun so far but i am having problems with the full auto fire mode. I have to dissasemble the gun and fool around with the selector and selector plate position in order to get it to fire full auto. But after using the selector switch a few times it is out of wack again. If anyone has encountered a similar problem please let me know if you have come across a more permanent fix. Also if anyone knows where i could get a reinforced selector plate for the ca36c let me know. I think this might help since the stock one is quite flimsy.
