Rubber Bullets (10) (5e Equipment)
From D&D Wiki
Any modern firearm which uses bullets for its ammunition can fire rubber bullets. Rubber bullets are non-lethal projectiles which can cause pain and incapacitation, but neither serious injury nor death. They are either entirely made of rubber or plastic or are simply rubber/plastic-coated.
Rubber bullets change the damage type of a firearm attack from piercing to bludgeoning, and inflict -1 points of damage per die. A creature reduced to 0 hit points by an attack using rubber bullets falls unconscious, but is stable and at no risk of dying.
