15 of the 144 gun stores and hunting shops we track in Montana have Class 3 / NFA. Full listings for every city are on the Montana page.

Google's category and hours fields have no way to flag a Class 3 Special Occupational Tax license — the federal designation that lets a dealer sell suppressors, short-barreled rifles, and other NFA items — so it disappears into the same generic 'gun store' pin as any shop that only carries standard firearms. Every store on this page has that status confirmed from its own website, FFL/SOT listing, or direct contact, not guessed from a review mentioning a suppressor in passing.

Call ahead before driving out for an NFA item. Class 3 inventory (suppressors, SBRs, full-auto) turns over slowly and stock varies a lot store to store, and the ATF transfer itself can take months, so confirm what's in the case and ask about their current average wait time before you commit to buying there.

Good to know

What is a Class 3 gun dealer?

It's a dealer holding a Special Occupational Tax (SOT) status on top of their federal firearms license, which lets them legally sell NFA-regulated items like suppressors, short-barreled rifles, and machine guns. Not every gun store carries this license, since it adds extra paperwork, fees, and ATF oversight.

How long does it take to get an NFA item like a suppressor?

After you pass the background check and the dealer submits your ATF transfer paperwork, approval has historically ranged from a few months to close to a year depending on ATF processing volume. The item stays in the dealer's safe under your name until the transfer clears, so you can't take it home the same day.

How to register firearm?

Firearm registration requirements depend entirely on state and local laws, as federal law does not mandate a universal registry for standard handguns or long guns. In Montana, specific transfer reporting or permit steps may apply when purchasing or importing a firearm. You can consult any of the 15 licensed FFL dealers in Montana for current compliance guidelines.

Can you get a concealed carry permit online?

Some jurisdictions allow applicants to complete classroom instruction online, but physical range qualification or in-person application filing is often required. Regulations vary across Montana, where specific state police or sheriff department criteria must be met. Check with local authorities or 15 registered FFLs across Montana for official permit procedures.
