Nope. You may not like the NRA and I don't expect everone to but they are the best lobbying group gun owners have. No one and I mean no one comes close. That's not my opinion. That's the anti's and groups that track lobbying groups.
That doesn't mean we should join the NRA and ignore the others. Personally, I like the Second Amendment Sisters and JPFO. Why? Because they can raise an awareness the NRA can't.
I would suggest joining the NRA, the GOA and your state association.
If you have to ask permission, it isn't a Right.
