Take a look at some of the pics I've posted...look at the damaged/crunched nozzle. I'm pretty sure that's it started off from some pretty nasty jams...and got worse with more use. To the point where it was not sealing at all. I ran it to destruction on purpose.
I'm not sure how the rifle can triple feed in full auto (or else it'd do it in semi too). Unless there is something majorly wront with your bolt/nozzle assembly and it's alignment/movement with the mag feed lips.
If you start with a clear chamber, full mag of gas and bbs, bolt forward.
- insert mag
- rack bolt all the way back, release
- remove mag
---how many BB's are in the chamber (you might need a rod to clear the barrel)? Should be one. If it's more than one you have an immediate issue with either the nozzle, the feed lips or the bolt. Repeat this test to see consistent results.
If you start with a clear chamber, full mag of gas and bbs, bolt forward.
- insert mag
- rack bolt all the way back, release
- semi auto fire 1 shot.
--shot should leave the muzzle, there should be one in the chamber (clear barrel to confirm. Repeat to confirm
If you start with a clear chamber, full mag of gas and bbs, bolt forward.
- insert mag
- rack bolt all the way back, release
- fire a short burst (ideally 2 shots...at most 4...whatever the number count how many shots)
-- did a shot come out each time?
But again...I wouldn't bother doing any of that until you get the knocker problem sorted out. If the knocker isn't hitting the main valve fully/repeatably...then it's not really going to help anything.
Ideally, you'd drop your rifle onto someone elses's lower trigger/grip assembly and isolate the issue in one go.

I've examined the nozzle/hopup/feed lips multiple times, and I still can't come up with anything that looks like it would cause any problems, so it has me stumped, even more so because it only happens in full auto rather than semi auto. Also, for each double or triple feed, there is a dry fire for each BB that was fired in the one shot, I can't remember if the blanks were before or after the double feeds, I think they were before... so wait now that I think of it it sounds like a jam, yea so why would the gun jam only on full auto?
