Question here, not just hunting....What are firearms regs for natives? Are they different on and off the reservation? No matter how much I'm willing to pay the state, I can't USE a suppresor or POSSESS a full auto (certain cases--class 3 gunsmith or military/LEO excluded) within Washington. Even if the natives don't use them for hunting, can they have them?
As far as hunting goes, most tribes have the same general firearm restrictions as the state. When it comes to gun control, I think all federal laws applies to natives on or off reservation. I'm sure it's a bit more complicated than that though...

So here’s the thing, for the most part natives don’t have to follow RCW Title 77 laws which are fish and wildlife laws. The only firearm law that is a title 77 law is the loaded firearm law, which applies to not only hunters but also basic people who have loaded firearms in their vehicles. All other firearm laws (that aren’t hunting laws) fall under the general crimes law either RCW 9 or 9A, thus they must follow them like any other citizen. So if you can’t possess a certain firearm, such as a fully-auto under state or federal law then a native can’t possess them either.
