Yes, burst triggers, also known as Forced Reset Triggers (FRTs) or rapid-fire activators, are illegal in some U.S. states like California and Oregon, and face legal challenges federally, though a recent DOJ settlement ended treating some as machine guns, it did not override state laws, making them generally prohibited or heavily regulated as multi-burst or rapid-fire devices. Federal law is complex, but state laws often ban them as they allow semi-automatic guns to fire much faster, acting like machine guns, with violations potentially leading to felony charges.

Is ATF banning binary triggers?

While the ATF hasn't issued a blanket federal ban on binary triggers, their status remains under scrutiny, with the agency previously targeting similar devices like forced reset triggers (FRTs), though some FRT restrictions were recently overturned in court. Binary triggers are designed to fire one shot on pull and one on release, operating differently from machine guns but facing potential regulatory action due to increased firing rates, similar to past battles over bump stocks. Currently, they are generally legal federally but face state-level bans (like in Minnesota, though recently challenged) and evolving ATF interpretation, suggesting future challenges are possible.

Can you get flagged for buying too many guns?

Yes, buying multiple firearms, especially handguns or certain rifles in a short period, can trigger reporting requirements and flag you for review by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) (ATF) and local law enforcement, as these sales are reported by Federal Firearm Licensees (FFLs) to help prevent illegal firearms trafficking. While there's no federal limit on the number of guns you can buy if you're eligible, buying multiple handguns (two or more in 5 business days) or specific rifles in border states requires FFLs to file a report (Form 3310.4), potentially leading to follow-up. 

Will SBR be free in 2026?

Yes, as of January 1, 2026, the $200 federal tax stamp fee for Short-Barreled Rifles (SBRs) and other National Firearms Act (NFA) items, like suppressors, has been eliminated, making the application process essentially "free" from that specific tax, though all other NFA regulations and background checks still apply.
