US12669303 - Firearm suppressor with gas recirculation and modular components

The present disclosure provides a firearm suppressor comprising a proximal end configured to attach to a firearm barrel, a distal end, and a housing disposed between the proximal and distal ends. The housing may include a gas recirculation system that includes return tubes configured to redirect gas from the central chamber to the peripheral chamber, and injection tubes in fluid communication with the peripheral chamber and a receiving baffle to extend gas dwell time. The housing may include, in combination or separately, a helical path assembly. Other innovative aspects, such as an identification plate system, baffle features, support lattice, etc., are also disclosed.
