SPAMF/Super SPAMF question

So as I plot out the final few details of my Top Secret Project(henceforth referred to as my TSP), I come to an idea for it that requires me to inquire about something that I cannot find an answer on.

Put simply: Can the 5-round Worker Eagle mag for the Harrier(this one - https://outofdarts.com/products/worker-harrier-eagle-5-round-magazine?_pos=1&_sid=a03608a18&_ss=r ) fit in a SPAMF or Super SPAMF? I've got three options before me for this part of my TSP and if this mag works with a SPAMF it would be by far and away the best option.

Help me finish my TSP! Enlighten me with the information I desire!
