Wyoming Suppressors & Silencers Laws (2026)

Suppressors & Silencers in states bordering Wyoming

The same rule in each neighboring state LawLert has verified, from that state’s own official source.

• ColoradoConditional

  Suppressors are legal in Colorado once they are registered with the federal government. A silencer is a "dangerous weapon" (C.R.S. 18-12-102, class 5 felony), but a valid federal National Firearms Act (NFA) permit is an affirmative defense, so a properly registered suppressor is lawful.

• IdahoConditional

  Suppressors are legal in Idaho, which has no statute banning civilian possession, and Fish and Game imposes no state restriction, so suppressors are legal for hunting all species. You need the federal ATF tax stamp under the National Firearms Act (NFA).

• MontanaConditional

  Suppressors are legal in Montana, where simply possessing one is not a crime. Under MCA 45-8-336 it is an offense only if the suppressor is possessed "with the purpose to use it to commit an offense." Suppressors registered under the federal National Firearms Act (NFA) are lawful, and hunting with sound-reduction devices is allowed.

• NebraskaConditional

  Suppressors are legal in Nebraska once you complete the federal National Firearms Act (NFA) process. Nebraska's prohibited-weapons statute (Neb. Rev. Stat. 28-1203) lists only machine guns and short rifles and shotguns, and silencers are not on that list. Nebraska legalized hunting with suppressors in 2014.

• South DakotaConditional

  Suppressors are legal in South Dakota for civilians who complete the federal National Firearms Act (NFA) process. SDCL 22-14-6 exempts anyone who has registered the weapon federally, and 2026 SB 2 removed silencers from the "controlled weapon" definition entirely. Hunting with a suppressor is permitted.

• UtahConditional

  Suppressors are legal in Utah, which has no state ban — they are lawful items under the federal National Firearms Act (NFA), obtained with an ATF Form 4 and the $200 stamp. Hunting with a suppressor is allowed: the Division of Wildlife Resources (DWR) big-game prohibited-weapons list does not include suppressors.
