I've never had the mag getting stuck problem no matter how tight I put that screw in (I over tighten screws a lot accidentally). I thought the mag catch was the piece that holds in the mag? They are referring to the piece that stops the bb from rolling into the receiver when it comes out of the mag, and the cylinder head nozzle has to push through to make contact with the bucking.

To me it sounds like it is both actually. I had the problem where you have to push the mag up to get it to feed on my Well MB-10. What I did was tighten the screws enough that it pushed the mag catch down enough to properly grip the mag, like Fuzzy said.

As for the "bb stopper" it sounds like it is either off center somehow (never seen that one happen but you never know), broken, or worn out. Have you tried taking your gun apart yet?

Take a few pictures of the bb stopper and the assembly put together for us. Also of the mag catch assembly.

If it was the bucking creeping back (happened to me recently) it wouldn't push the bb back into the receiver. If it was preventing feeding it wouldn't feed if he pushed the mag up if the bucking was blocking the bb.

You're right, I didn't think of that. Again this begs the question "have you tried taking your gun apart yet?"

So the new mags feed fine but the original doesn't? the part the mag catch clips into might be too deep and it doesn't pull the mag up all the way. Just to clarify, this only started happening after you took it apart?

I have seen spare bb catches on various websites like ehobby asia. The part I can't find is a spare hopup arm (besides the danger werx arm) so I can test out different nubs and still keep the stock nub. But thats besides the point. If it suddenly started working with these new mags I have no idea what could have been wrong to make the original mag make the bbs roll into the reciever. Are the bbs still rolling in the reciever or did that sttop too? As for the wobbly mags, just put a strip of electric tape on either the back of the mag for a tight fit or the side for less room to wobble.

the mag catch stays in place when you tighten the stock screws and the hopup block (the metal block the stock screws into right under the hopup) pushes into the mag catch, thus holding it down. If it seems like it's pushing into the stock you might not have it tightened enough, or you might have something in the way. No need for glue.

As for the arms, we couldn't find any anywhere except for dangerwerx arms which cost 22$ at ASGI (can you say "rip off"?), but Cheese is in the process of making aluminium arms to sell them. Not to advertise cheese's stuff, but I can't wait for it.

They just did come out. He put them on shapeways. Go to the cheese man industries thread in commerce, and on page 3 search for the link.
