Everything People Want from a Smart Gun, Without the Compromises

For years, people have loved the idea of a biometric that restricts a firearm to just authorized users. Now, B.O.S. Lock lets you program only the fingerprints of people who should have access to your firearm and locks out everyone else. It also comes without the compromises more tech would bring in:

No compromises of connected systems

  • No Wi-Fi, Bluetooth, or cellular
  • No firmware updates needed to work
  • No accounts or logins
  • No network required

Why We Built It

When our founder, Keith Bombaugh, became an uncle, he faced the same decision many responsible gun owners face: He wanted his firearms secured from curious hands and ready if he ever faced unannounced danger. The devices he tried forced a trade-off: quick access when you need it, or real protection from curious hands. He built B.O.S. Lock so people no longer have to choose. The goal is simple: protect the people you love and be prepared to defend them with a device that turns a secured pistol into a ready pistol in moments.

Will Fusion Fit Your Gun?
