Gen 1 Marauder

What is the internal diameter of the Gen1 Marauder's 22 cal factory transfer port? I've searched the net but can only find the sizes of replacement ports. BTW I ordered a .160 diameter port.

measure it. I actually ported mine out basically as far as I could take it. Mine is a .22 gen 1. I have done a ton of work to it.
