Are Suppressors Legal in Oregon?

Oregon Revised Statutes section 166.272 addresses possession of a firearm silencer and supplies an affirmative defense for a silencer registered as required under federal law. That structure makes the approved registration evidence important if the device is possessed or transported in Oregon.

Suppressors are federally legal to own under the NFA. As of January 1, 2026 the One Big Beautiful Bill Act (signed July 2025) zeroed the federal making and transfer tax on suppressors, formerly $200. Form 4 or Form 1, fingerprints, the NICS background check, and NFA registration are all still required; ATF eForm approvals currently run days to a couple of weeks.

Scope: Firearm suppressors (silencers) as defined by the NFA. Federal NFA compliance (Form 4 or Form 1, fingerprints, NICS, registration) is required everywhere they are legal.
