M-LOK Picatinny Rail Adapter X Magpul AFG 2

What size M-LOK Rail Adapter would fit nicely with the AFG 2 without being over or undersized? I was thinking the 9 Slot would be just fine but I’m not sure because everything online looks oversized to me.

You need one that covers 3 mlok slots iirc.

Edit: magpul makes one:
