US12638260 - Systems and methods for enhanced firearm suppression

A firearm suppressor. In an embodiment, the suppressor includes an outer tube and a baffle core disposed within the outer tube. The baffle core includes a body having an exterior surface spaced from the inside surface of the outer tube. A bore extends through the body from an inlet to an outlet permitting a bullet to pass through the baffle core. A plurality of slots or through holes extend through the body between the bore and the external surface of the body permitting gases to expand outward toward the outer tube. A plurality of blind cavities are formed into the external surface of the body and extending into the body without penetrating the bore. These blind cavities provide additional surface area and slow the exit of gases from the suppressor and further cool the gases.
