"Close to mid-range 9mm submachine gun with low recoil and a medium fire rate. Favored by BOPE."
— In-game description

The M12 is a submachine gun featured in Tom Clancy's Rainbow Six Siege. It was introduced in the Operation Skull Rain expansion pack and is available for use by the Operator Caveira.[1]


The slowest firing weapon in the game, the M12 is a fairly weak submachine gun for close-range engagements and nearly unusable for long-range. Its slow rate of fire does, however, make the gun's recoil easy to control. It's suited for a more methodical playstyle thanks to having the tightest hipfire accuracy out of all submachine guns.

  • The M12 in reality fires in an open bolt configuration, meaning that one in the chamber would be impossible, unlike the in-game counterpart, which holds one in the chamber. This error is shared with other guns with an open-bolt configuration.
