MP5 Cycle issues

[scotty.1]

I have an mp5 I am fixing at the moment. Got it working but it now and again shoots 2 BB's but will cycles twice. So the first cycle it wont shoot a BB and the second cycle it shoots 2 BB's. Any clues???

Sounds like nozzle/ tappet plate issues.

Check your hop unit is properly engaged with the gearbox.

You may have to crack the gearbox open and check the tappet plate is sat properly, the nozzle is engaged in the groove in the tappet plate (not sat either side of it) and that the tappet plate spring is seated properly.

First instance check the hop rubber/ hop assembly.

Could even be as simple as cheep bb's.
