Legal
Yes. Nevada's rate-of-fire ban does not reach binary triggers, which still require a separate trigger movement per shot.
Contested entry
NRS 202.274 (AB 291, 2019) bans devices that eliminate the need for a separate movement for each function of the trigger. A binary trigger requires the operator to release the trigger for the second shot, so it is not covered. Note the asymmetry: NV DOES ban FRTs under the same statute.
The statute in practice
Nevada Revised Statutes section 202.274 turns on whether a device eliminates the need for a separate movement for each individual trigger function and materially increases the firing rate. A binary trigger still requires a release movement for its second shot, so that precise movement language—not the device's cyclic speed—is the central textual question.
Federal law
Binary triggers are legal under federal law and are not machine guns under 26 U.S.C. § 5845(b); ATF treats the trigger pull and the trigger release as two separate functions of the trigger, so one round is fired per function. Cargill v. Garland (2024) concerned bump stocks, not binary triggers, and does not change this.
Scope: Binary triggers (Franklin Armory BFSIII and similar): fire one round on trigger pull and one on release. Forced reset triggers are a separate class.

What to buy
In a green state, these are the binaries that matter. Franklin Armory's BFSIII line covers AR, Scorpion, Stribog, and B&T hosts, and the Fostech Echo AR-II is the drop-in AR alternative.
