It fits into 2" ID tubing..
Not sure if they fixed it or not, But I ordered one several months ago, and the corners of the square tube were not radiused... SO it didn't fit into a receiver.. I had to knock the corners down to make it fit...
They told me that they were going to fix the problem.. Hope they did for ya

The Company converted from Korean to Chinese steel. Thats when the radius appeared.
Gary, is this for your 60? Ever get the diesel in it?
Assuming that current production is anything like the older unit that I had to study for a couple of weeks it is a big rivet. It is not something pivoting about an 'axle' (like the M416 lunettes), it is more like a thrust bearing arrangement where the loads are on the two opposing faces.
Just for any future readers, you need "receiver tube" such as this: http://www.curtmfg.com/Category/95/Receiver Tubing
This isn't something you can pick up at a local steel supply place, at least not around here. There is slight but important dimensional and radius differences between this and regular 2.5" Square x 1/4" Wall Tubing.
For instance the old design or shall I say "Gen 2" of the Max Coupler used square stock with hard 90 degree edges. Due to the design of regular tubing, it would not fit in it. However it did fit in "receiver tubing" since the inside corners do not have a radius.
I had called and emailed Kilby right after they came out with the "Gen 2" to let them know this could be a problem for some people using regular tubing or imported receiver tubing. I'm happy to report that we just received the latest "Gen 3" that has the corners radius'ed to avoid any problems with receiver tube variation.

As noted it is a special mill run of tubing used for receiver hitches. What makes it different isn't just the corner radii, it also does not have any interior flash like 'normal' steel tube can have. In a way it is square DOM. Two of my local steel vendors stock receiver tube in 20' randoms, so availability is very location dependent.
I just purchased the Max Coupler for my M416. I changed to "receiver tubing" instead of the lunette setup. My local steel vendor had remnants of receiver tubing that I bought at a discount. I also bought a short piece of larger receiver tube so that I could make a .50" piece to cover (welded) the end of the receiver tube so that the receiver tube didn't deform from use. I used my cut off saw to cut to length. You'll need to drill holes for the receiver pin. Quarter inch tubing is the best, although a bitch to drill.
Guys, be aware of the 2 In tube you buy for your receiver, there is a rated steel with DOT specs that should be used, not readily available in a lot of areas, Industrial Metal is the one source that does carry it. If you use the foreign or unrated material be cautious. I think this all revolves around weight, torque etc. Didnt see the post ahead of me it clicked as I clicked but you gert the idea Be safe
^^^ I never thought of that! Do they heat treat some to make them stronger?

I have wondered before if there was a difference between 2.5" x 2.5" x .25 steel an receiver tube. Makes sense, though.

What size is the nut/bolt. I don't have a wrench or socket that size.
To answer my own question... 1-7/16 in. Socket or wrench works.
