Oregon has over 50% ownership, placing it in the highest tier of gun owning states per capita, according to data from 2022, I’ve seen various numbers though, increasing in later years so it may be higher now. Ancedotally though the majority of people I’ve known in Oregon had at least one firearm. Armed right wing ‘sovereign citizen’ groups have stood up to feds multiple times in the state, and there are several known anti-government militias based in Oregon.
