Wolverine Hydra Gen2 m14 jamming open on empty

I'm at my wits' end with this issue. The gun works amazingly well up until I take the mag out and have to clear it when it has a tendency to jam up. The first shot gives a disheartening click as something doesn't quite work properly and if the trigger is pulled again it jams the HPA engine open, allowing a bunch of air to leak out until I disconnect the line. I had a look today and there's a BB rolling around in the hop unit from what I can see after that first disheartening click shot and when it jams open I can't see the nozzle jammed inside the hop unit so it's not the hop rubber stopping it from returning back as it's an open bolt system. I've tried the following and none have worked:

 

- Using a higher psi. I typically set it to 60psi so I can run it at 1.1J so I thought that maybe it was too low, even though Wolverine say 60psi is fine. Tested it at 80psi to make sure and still getting the same issue.

- Attaching a strip of a drinks can around the bottom at the back of the hop unit as there's a small gap that I thought BBs were falling through. Didn't fix it.

- Removing the metal thing that clips over the top of the hop unit underneath the bolt and dust cover. This partially worked, but it still did it from time to time and also potentially exposed the hop unit to the elements were I to do it in game

 

I was just wondering if anyone else here has built a HPA m14 and had the same issue as me, and if so how the hell did you solve it? I love the gun otherwise, but this one thing really ruins the whole thing.

Is the nozzle centred into the hop unit . Look down the barrel with torch up the feeding hole of the nozzle . See if all centred ?

Being totally honest, I can't tell. Tried looking down with a torch shining up into the hop unit but can't make it out at the bottom of the barrel. It would make the most sense though, as when I spoke to High Pressure Airsoft they were a bit confused but said that misalignment would be their best guess. If that's the case, I'll probably end up sending it to High Pressure Airsoft because I just don't have the tools to sort it out.
