Circuit Breaker

The Circuit Breaker is a unique legendary 10mm pistol in Fallout 76, introduced in the Expeditions: Atlantic City update part one, Boardwalk Paradise. It takes fusion cells, rather than 10mm rounds, and thus deals energy damage instead of ballistic. It also has a special "Last Shot" mod that causes an explosion that deals damage and stuns nearby enemies on the last shot in a magazine.

Characteristics[]

The Circuit Breaker has the following special abilities:

• Anti-Armor - Ignores 50% of your target's armor
• Custom mod - 15% faster reload speed
• Special Last Shot:
  • The last shot in a magazine will deal extra energy damage^{[note 1]}
  • Produces an explosion that deals energy damage^{[note 2]}
  • Stuns enemies within 50 feet

The Circuit Breaker uses different mods than the 10mm pistol, most notably lacking the suppressor and automatic receiver mods.

• Paints for the 10mm pistol cannot be applied to the Circuit Breaker.

Bugs[]

• PC Xbox One Playstation 4 The +15% reload speed description does not match the +5% reload speed the circuit breaker's custom mod actually adds.^[2][patched]
• PC Xbox One Playstation 4 The aligned grip mod requires scrapping 10mm pistols to learn, instead of unlocking with the weapon.^[3][patched]
