I didn't find this immediately on this board, so I am starting this thread. Sorry if it's been discussed before. I moved here a long time ago, but only recently have looked into suppressors. I've used them at ranges in the military, and in several other states. Thay are quite nice to use and make shooting ranges far better on the ears. OK, So it's legal to buy, own, and walk around with a suppressor in WA.... Just pay the FED $200 tax stamp and do the paperwork. Order what you want and wait for the suppressor tax stamp to arrive. But it's NOT legal to put a round through one anywhere in state? Can we do something about this?
