When the tube of your hopup descends into the mag, it pushes aside a small piece of plastic which acts as a gate for the BBs. The part of the gate that the hopup tube engages is diagonal. Sometimes this gate is too long or the angle of diagonal bit is incorrect.

Either way the fix is to file it down a tiny bit, like this:

"Mah check"

Now you know
