Initiative I 1639 now requires WA residents buying a semiautomatic assault rifle to first take a training course. (Among other new requirements). One gun store has one online for free. Good for five years. So if you are looking to buy or inherit a Ruger 10/22 rimfire or Grandad's Garand, this would be good value. Other courses I have seen offered cost upwards of $75.

Might be interesting for others looking for training, or curious about the new laws, tho out of state residents can no longer buy semi auto rifles in WA.
