NRA membership represents about 2% of gun owners in the USA. Their prime directive is generating revenue and consolidating control of the firearms discussion.
The NRA wants, no demands, a 100% monopoly on firearms training, gun ranges, CCW training and certification, and whatever other segment of the firearms market they can get.
People used, bought, sold, traded, made, and trained with firearms and related equipment long before the NRA existed. People discussed firearms ownership long before the NRA enter the conversation.
The NRA has some useful training materials and info, but it is only ONE of MANY sources for such training.
Any group trying to establish a monopoly on any segment of a free society should send up warning flags for everyone.
Just why do you think the President was so quick to blame the NRA for defeat of the latest gun legislation?
