CSSA: I think they're dormant. I've been a member but haven't heard from them in a while.

RMGO: Controversial. I'm a former member and not a fan at all, mostly due to their spokesman. He's a member here and I don't want to raise the ire of our hosts by being too expressive. NAGR is the same guy. If NAGR is relevant on the national level, I've not heard of it.

SAF: IMHO they're a big deal. SAF was a major player in a few very big RKBA court cases (They took on Heller before NRA jumped on the bandwagon, for instance) and IMHO do more to advance RKBA through the courts than anybody else.

CMP: Not a political organization at all. Originally, they were created as part of the Dep't of Defense to advance marksmanship training among civilians, but they're more or less independent now. They sell surplus M-1 Garand rifles and a few other things and promote a few shooting matches, mostly under NRA High-Power rules. Them, I AM a fan of. They gave me a screaming deal on a 1930's-era assault rifle, after all.
