The fix is to change it out.
Then use less oil when lubing your mags and don't apply it to the rubber.

I did a bunch of research before purchasing the gun. I am aware of this issue and only put one drop of oil on my propane tank before installing the nozzle. I highly doubt my bucking is swelling when I have only put 4 or 5 magazines through the gun. Would that cause double feeding anyways? a BB always fires, none ever get stuck in the barrel, just double fed for some reason.
I am going to try some BB Bastards tomorrow and hope it solves the problem.
