gun jamming without identifiable reason

My gun (echo 1 mp5 Master series) has started jamming without any notable reason, I've lubricated the barrel and tried both gearboxes, and they both have the same effect.

Any ideas?

Turn the hopup all the way off & make sure the bucking is lined up

Nope, everything's fine there, lined up just fine the other thing is its not constantly jamming only every 20 or so rounds.

Try different magazines or a different brand if all are the same kind.

that's probably the next step but (being terribly dumb here ) why would the magazines be at fault? Misfeeds?

Spring tension,

If you are running High, Mid or Low Caps, the weaker the spring gets the slower the magazine feeds.

That makes sense, so..... Now what do I do? Restock on mags?

Just try someone else's mag set first to confirm that it is your mags.

If your high caps are losing tension at only a few rounds or so, then perhaps it's time to invest in some new Lonex Flash Mags

How long have you had the mag? The spring may be weird. If its putting TOO many bbs into the barrel then load the mag overnight and just let the spring sit, it should weaken the spring and put the right amount of bbs in.

PS Slobs, I love your pic

The mags are first year if I can remember. I haven't put more than 5,000 through each mag. It makes sense that it would be the magazines now, I ran semi fire through it and it ran fine, then automatic for twenty shots and it started to act up.

Yeah its most likely the mags, borrow a friends new mag or something... just try one out that hasn't been used much and isn't too old. Good luck
