Having been inside the NRA during the time about which Barrett is writing (I was associate editor of American Rifleman from October 1990 to April 1994), his characterization of the organization at that time is pretty spot on.
But, given how the gun control fight was trending in the early 1990s, how firearms groups and manufacturers were beginning to splinter under the pressure, I don't think NRA's leadership had any other option available than being the 800 pound gorilla with an axe handle.
Barrett's book, I thought, was an excellent survey overall of psyche of the times and the psyche of some of the people involved. I met a number of those people at the time, and some of the stories that were circulating then, stories that weren't touched on in the book, were even more interesting.
