Key Notes

Ballot Measure 114 (permit to purchase and 10 round magazine limit) is not in effect: HB 4145 (2026) delays it while the Oregon Supreme Court case is pending. SB 243 (September 2025) bans rapid fire activators, including FRTs, binary triggers and bump stocks. Private sales require background check via FFL.

•No (Measure 114 permit delayed to Jan 2028) Permit to Purchase — HB 4145 pushed the permit requirement to January 1, 2028, and the state constitutional challenge is still before the Oregon Supreme Court.
•No (Measure 114 limit not in effect) Mag Limit — Measure 114's 10 round magazine limit is not in effect; HB 4145 (2026) delays it while the Oregon Supreme Court case is pending.
•Shall Issue (Concealed Carry) — Oregon must issue a Concealed Handgun License to qualified applicants. Training and a background check are required.
•Yes (locality restrictions) Open Carry — Open carry is generally legal, but cities including Portland restrict open carry of loaded firearms within city limits.
•Yes (Background Check Private) — All private sales must go through a licensed dealer (FFL) for a background check.
•Unrestricted (NFA) — All NFA items (SBRs, SBS, suppressors, machine guns, destructive devices) are legal under state law. Federally, ATF announced on October 9, 2026 that it would stop enforcing the National Firearms Act's approval, registration and tax stamp requirements for suppressors, short barreled rifles, short barreled shotguns and any other weapons (AOWs). This is an enforcement policy, not a change to the National Firearms Act; the law is still on the books and the policy can be reversed or challenged. Machine guns and destructive devices still need ATF approval.
•Partial (State Preemption) — Since SB 243 (September 26, 2025), local public bodies can ban concealed handgun license holders from carrying in public buildings.

How Oregon Law Affects Your Build

Plain-English implications for builders, derived from the regulations above.

Standard AR-15 Configurations Allowed

Oregon does not restrict semi-automatic rifles by feature. Standard AR-15 configurations — including pistol grips, collapsible stocks, threaded barrels, and flash hiders — are legal for sale and ownership.

NFA Items Permitted

Oregon allows ownership of NFA items under state law, including suppressors, short-barreled rifles (SBRs), and short-barreled shotguns (SBS); machine guns still need an approved ATF transfer. ATF announced on October 9, 2026 that it would stop enforcing the National Firearms Act's approval, registration and tax stamp requirements for suppressors, short barreled rifles, short barreled shotguns and any other weapons (AOWs). This is an enforcement policy, not a change to the National Firearms Act; the law is still on the books and the policy can be reversed or challenged. Some states only allow suppressors and SBRs that are federally registered or possessed in compliance with federal law. Check your state's statute before you buy.

Background Checks on Private Transfers

Oregon extends background-check requirements beyond licensed-dealer sales (Yes). Private transfers of complete firearms typically must run through an FFL.
