Yes, you're good to go in Washington. Hope this helps.

Ricardo, yes Sir it is as legal in the State of Washington as it's State Bird the American Goldfinch. There are no Washington restrictions other than needing to be a minimum of 21 years of age to purchase. Cheers and stay safe!

Yes this is legal in Washington state, it is a rifle with a 16.2" barrel, it has a decorative fake suppresor over the barrel, that makes it look shorter then it really is.
As long as you are at least 21 your good to own this in WA.
