There's certainly some sketchy stuff that's gone on behind the scenes as the organization definitely isn't the same today as it used to be in previous times.
While it's not a bad thing to bust up an org that's misrepresenting their 501(c)(3) status, I do think it's politically motivated and isn't likely to accomplish what they think it will accomplish.
The NRA gave $30 million to the Trump 2016 campaign, and were almost certain to repeat that (and maybe even bump up the amount) for 2020.
So if you get rid of the organization that's giving money to Trump, you cut off a source of funding for him. Sounds logical on paper.
However, that's not likely how it would play out.
It's likely that any NRA donors (who would typically contribute to NRA, then NRA executives would by themselves a steak dinner, a vacation, and then give what's left over to the GOP), would instead just end up donating directly to the Trump campaign with that money...which would actually mean more money for Trump after you cut out the siphoning middle-man in the equation.
Or they give that money to another pro-Trump org that's even better organized than the NRA which would mean, again, more money getting thrown toward Trump.
You'd think that if cutting off as much funding from Trump was really the goal, they'd bask in the fact that most of that money that Trump supporters are spending for what they think is supporting his cause, is actually getting siphoned off and not going to that cause.
For example, PETA would be thrilled if they found out that most of the money people were donating to a "pro-factory farming" organization was actually just going to buy a vacation home and not actually going toward factory farms...and wouldn't want to change a thing.
Now, if the motivation behind this was strictly to deal a blow to gun rights advocacy, shutting down the NRA is definitely going to backfire. Without the NRA in the way, the #1 national gun rights advocacy non-profit will be the 2nd Amendment Foundation.
...for those unfamiliar with that organization, they're much smarter, better organized, have more competent lawyers, and are actually responsible for the court rulings that have been "big wins" for gun rights advocates (DC v. Heller...striking down of concealed weapons bans in various states, etc...) -- even though the NRA tries to steal credit for those, it was actually 2AF that got those wins in court.
With the NRA no longer available to donate to, it's almost certain that a substantial portion of that $$$ will end up in the hands of the 2nd Amendment Foundation, and if they can land rulings like DC v. Heller, getting waiting periods shot down in California, getting rid of Illinois' ccw ban, etc... and do it on the comparatively shoestring budget compared to the NRA...Imagine what they'll be able to do with the newly found tens of millions of dollars.
2AF pulled all of that off on 4 million dollars a year, NRA has half a billion...and to my knowledge, pretty much serves the purpose of selling branded tote bags, bumper stickers, making Wayne rich, and keeping Ted Nugent relevant.
When you look at the NRA leadership structure, you find a Huckster, some b-list actors, an obnoxious rocker from the 70's and 80's, etc... You look at 2AF, you find high end attorneys, people with PhD's who've published numerous books, etc...
If you want all of that gun advocacy money to fall into the hands of an organization that's far more competent and capable, by all means, get rid of the NRA.
If you're looking to hamstring the movement to get rid of all meaningful gun legislation, you want "unrestricted gun rights advocacy money" going to Wayne LaPierre's "fancy dinner and suit fund", not going to Alan Gottlieb and Alan Gura to travel the country getting gun laws struck down with relative ease.
