Suppressor law
Carve-out in flux
Legal, but the state exception is written for federally registered owners. Since the ATF's October 9, 2026 policy, new purchases cannot register — the statute is untested for them.
| Statute | MCA 45-8-336; MT DOJ legal guidance (Aug. 27, 2026) |
| Notes | GAP FLAG: 87-6-401(1)(c) is keyed to ATF registration, which ATF no longer requires/enforces for covered suppressors; no Montana fix found (legislation introduced ahead of the 2027 session per AG guidance). Montana's sawed-off/SBS exemption likewise remains keyed to a valid federal tax stamp. |
| Hunting | Conditional - MCA 87-6-401(1)(c) prohibits hunting with devices to 'silence, muffle or minimize' firearm sound unless the device 'is registered with the ATF' - so hunting with a post-Oct 9, 2026 unregistered covered suppressor would violate this provision as written. |
Federal context: suppressor tax $0 since Jan 1, 2026 (OBBBA); ATF stopped enforcing NFA approval/registration Oct 9, 2026. State law is unchanged and independently controls.
