Default AR-15 barrel manufacturer identification

I have this barrel, it is 20" with a H-Bar profile and it only has "2N" marked on the barrel. No caliber or twist rate.

Anyone know who may have made this barrel?

Rock River Arms.
There might be some more characters under the barrel nut.

Thank you. Any idea of twist rate? I can't seem to get an accurate reading from my bore brush technique. lol

ETA: Pretty sure I found that info on the .net as 1:9".

The default twist for a Rock River of that age is 1:9".
Being a 20" barrel, you can shoot up to 77gr bullets.
