Renders the wielder invisible when reloading an empty clip. Extra damage while stealthed.

For the NPC, see Frifle and the Grey Mauser.

Grey Mauser is a gun that makes the player invisible when they reload an empty clip, which prevents enemies from noticing the player and allows the player to steal from shops.


  • Synergy.png Guns and Deviltry - If the player also has Winchester Rifle, the guns' damage are increased by 25% and they fire a knife whenever they are reloaded.
    • The knife deals 8 damage, can stun, and causes an aesthetic bleed effect.


  • Any action, besides walking and stealing, will remove the invisibility. Shots fired while invisible deal quadruple damage.
    • Stealth from other items such as Box will also grant bonus damage.
    • Followers like Wingman will not shoot while the invisibility effect is active.


  • UnusedSynergy.png Unused: The Great War - If the player has M1, it causes an unknown effect.
