The Good Book
I own all of the above titles, (and over a dozen others), and if you are looking for an easy to use, clear, concise book on how to build an AR, I would say none of the above.
I would recommend "The AR-15 complete assembly guide" by Walt Kuleck and Clint McKee. It is well written by a couple of very knowledgeable guys that have built a "few" AR's. It has clear 'photos, a logical sequence, and lists comprehensive checks, tips, and safety information.
Of course, anyone interested in the AR should also have the above titles in their library, although the author of "The Black Rifle II" lost a bit of credibility when he decided to cut and past his photo on a few backgrounds.
Regards.
