Disclosed is a rifle grenade using a bullet trap. A propellent assembly is formed with a first housing configured to house a trapping unit that traps a bullet shot from a gun to travel from rear to front and absorbs kinetic energy of the bullet, and a second housing configured to house a propelling unit that is disposed in front of the first housing, and is activated by the kinetic energy of the bullet which is absorbed into the trapping unit to provide a propelling force in a trajectory direction of the rifle grenade.
