Class 3 / NFA Dealers in Montana

8 of the 92 gun stores we track in Montana have Class 3 / NFA. 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. Full listings for every city are on the Montana page.

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.
