US12687366 - Cleaning apparatus for sealed firearm suppressor

A cleaning apparatus for internally cleaning firearm suppressors is disclosed. The cleaning apparatus includes a reservoir configured to contain a cleaning fluid, a pump in fluid communication with the reservoir, and a spray tube coupled to the pump and dimensioned to be insertable within a firearm suppressor. The spray tube includes a sealed distal end and a plurality of apertures arranged to discharge pressurized fluid radially outward, with alternating patterns along opposing sides. A fluid return system collects the discharged fluid and recirculates it to the reservoir via a fluid return connector positioned above the reservoir floor to minimize particulate intake. The apparatus may include a cylindrical reservoir supported by a base housing, compression fittings, a removable lid, electrical controls, and an accessible drain assembly. A support structure holds the suppressor in a vertical orientation with drainage clearance. The system enables efficient, contained, and repeatable internal cleaning of firearm suppressors.

Claim 1

1 . A cleaning apparatus for internally cleaning firearm suppressors, comprising: a reservoir configured to contain a cleaning fluid; a pump in fluid communication with the reservoir and configured to pressurize the cleaning fluid; a spray tube having a proximal end and a distal end, the proximal end being coupled to the pump, the spray tube including a plurality of apertures distributed along a length thereof and configured to discharge the pressurized cleaning fluid radially outward, wherein the spray tube is dimensioned to be insertable within a bore of a firearm suppressor; and a fluid return system configured to collect the cleaning fluid discharged from the firearm suppressor and return the collected cleaning fluid to the reservoir for recirculation through the pump. a reservoir configured to contain a cleaning fluid; a pump in fluid communication with the reservoir and configured to pressurize the cleaning fluid; a spray tube having a proximal end and a distal end, the proximal end being coupled to the pump, the spray tube including a plurality of apertures distributed along a length thereof and configured to discharge the pressurized cleaning fluid radially outward, wherein the spray tube is dimensioned to be insertable within a bore of a firearm suppressor; and a fluid return system configured to collect the cleaning fluid discharged from the firearm suppressor and return the collected cleaning fluid to the reservoir for recirculation through the pump.
