i had this issue with my G36 when i first got it, the problem is fairly easy to fix.
its not the tappet plate or the nozzle. its in the hopup assembly.
if you look at the hopup assembly, on the underside of the area just befor the entrance to the hopup openning, there is a small spring mounted ramp.
that ramp is there to stop BB from being pushed into the hopup more than one at a time, but if the mag spring is a little too strong it will push a second BB up and the first BB forward.
to fix this all you need to do is take apart that ramp assembly and replace the orriginal spring with a stiffer one. thats it, and after that it should feed fine.
