First off, the NRA was never about the Second Amendment, that has been a recent development. The NRA coined the phrase 100+ years ago, “Sporting Purposes of Firearms”. The NRA gave us every last federal, and many State, gun control bills for the past 100 years, including the 1934 NFA and the 1968 GCA.
Until the NRA starts undoing the damage they did in those bills they will never have my support.
More recently, in Wyoming: NRA pushing gun control in Wyoming? Gun Control bill sponsor says that the NRA drafted and supported his gun control scheme.
