Unfortunately, my ears are both plugged up ever since I flew to Virginia earlier this month. Given that, and the fact that the audio I got from the clip was pretty crappy (at least it sounded crappy to me), I have no idea what was said. From what I've heard and read, Bruning is pro 2A, and regardless of what he actually said, I doubt he intended to criticize the NRA so much as to emphasize his beliefs in 2A rights.
I didn't know anything about the NRA supporting Ashford's assault weapons ban, so I can't really comment on that except to say that I'm surprised the NRA would support something like that. I'm guessing there is more involved here than I know. I will say, that for many gun owners (or anyone who believes in the right to keep and bear arms), it's not a question of demanding complete freedom regarding the issue, but more in securing what is considered possible in the face of anti-gun opposition.
Yes, I'm well aware that many here, are the "cold dead finger" types who adamantly deny that government has any right to infringe upon their own rights. They refuse to compromise their principles, and I don't fault them for that. In reality though, most of them "capitulate" (no negative inferrence intended) and go along with whatever the law allows. They submit, if you will, because the options are pretty bleak: to become a survivalist and hide out in the boondocks somewhere, or become an anarchist and fight to the death with our own police or military (sorry, you're going to lose).
I think we need a balance of both schools of thought: those who demand totally uninfringed gun rights, and those who are willing to compromise in order the get the best they can hope to achieve. Having the former puts enough fear into the anti-gunners that it gives them an incentive to compromise their just-as-adamant beliefs that we should have no guns at all. Having the latter gives us the numbers we need to get politicians to listen.
So, many pro-gunners resolve themselves to fighting for the best laws we can hope to get passed rather than wasting time arguing for something that is highly unlikely to ever become reality.
