    If it's a RRA barrel (I know you mentioned a custom builder in there somewhere...), you might look up "Wilson Barrels", as I believe thats who RRA has used for a number of years... Good luck, and Welcome to The High Road!

    I built a RR with that same bbl configuration and it is marked identically. Had occasion to send that upper back to RR & queried them as to mfgr.........as stated they stated Wilson..........utterly zero idea as to the meaning of the coding. (great shooter, tho)

    A bit off topic; but how do you get certified as a "Master AR Builder" and who does the certifying?
