Just attended the Colt armorer's course two weeks ago with Allan Offringa - my second course with Allan.
He (Allan) made a specific note/point about the Colt Operation and Unit Maintenance Manual (armorer's manual) provided for the course.
The manual was written by Christopher Bartocci when he was employed at Colt.
Chris has published an armorer's manual for what seems to be a reasonable price at $40 per copy.
I have a copy of the manual ordered and while I don't know yet, suspicion it's probably good to go given his background - happy to give you a report once in hand.
Additionally, just as an FYI, Larry Vickers newest Vickers Guide AR-15 book lists Bartocci as one of the authors.
The new Vickers book, in my opinion, is fantastic - I splurged for a signed copy and was fortunate enough to get one of the books also signed by John Meyer.
Assuming you took Wayne Dobbs up on his offer, you're probably good to go.
Curious if you are set with the info/knowledge you were seeking?
