Is anyone in the know?

If I remember right, different barrels often use different sizes but if you need I can check tomorrow but,

Any o ring that causes enough friction to prevent the barrel from turning back out is all you really need

They are also not needed at all so unless you are having problems with your barrel unscrewing I wouldn't worry about it

Yep, I came here to say this. Cram one on that fits to feel.

I always used tank O-rings, or something of that specific size.
