The NRA Supported the National Firearms Act of 1934
In fact, they've supported gun rights infringements "since...1871."

"The National Rifle Association has been in support of workable, enforceable gun control legislation since its very inception in 1871."
—NRA Executive Vice President Franklin L. Orth
