Abstract

Disclosed herein are systems, devices, and methods for use in reducing the heat emission of a firearm noise suppressor.

Claims

exact text as granted — not AI-modified
1 ) A device for reducing the heat emission of a noise suppressor comprising a cover comprising a heat-resistant fabric layer and a metal layer. 
     
     
         2 ) The device of  claim 1 , wherein said metal layer comprises aluminum. 
     
     
         3 ) The device of  claim 1 , wherein said heat-resistant fabric layer has an LOI of at least 25. 
     
     
         4 ) The device of  claim 1 , wherein said heat-resistant fabric layer has an LOI of at least 35. 
     
     
         5 ) The device of  claim 1 , wherein said heat-resistant fabric layer has an LOI of at least 45. 
     
     
         6 ) The device of  claim 1 , wherein said heat-resistant fabric layer has an LOI of at least 55. 
     
     
         7 ) The device of  claim 1 , wherein said heat-resistant fabric layer comprises Oxidized Polyacrylonitrile (OPAN). 
     
     
         8 ) A device for reducing the heat emission of a noise suppressor comprising a carry bag comprising a heat-resistant fabric layer and a metal layer. 
     
     
         9 ) The device of  claim 8 , wherein said metal layer comprises aluminum. 
     
     
         10 ) The device of  claim 8 , wherein said heat-resistant fabric layer has an LOI of at least 25. 
     
     
         11 ) The device of  claim 8 , wherein said heat-resistant fabric layer has an LOI of at least 35. 
     
     
         12 ) The device of  claim 8 , wherein said heat-resistant fabric layer has an LOI of at least 45. 
     
     
         13 ) The device of  claim 8 , wherein said heat-resistant fabric layer has an LOI of at least 55. 
     
     
         14 ) The device of  claim 8 , wherein said heat-resistant fabric layer comprises Oxidized Polyacrylonitrile (OPAN). 
     
     
         15 ) A method of reducing the heat signature of a firearm suppressor, said method comprising attaching a cover to the firearm suppressor prior to use of the firearm, said cover comprising a heat-resistant fabric layer and a metal layer. 
     
     
         16 ) The method of  claim 15 , wherein said metal layer comprises aluminum. 
     
     
         17 ) The method of  claim 15 , wherein said heat-resistant fabric layer has an LOI of at least 25. 
     
     
         18 ) The method of  claim 15 , wherein said heat-resistant fabric layer has an LOI of at least 35. 
     
     
         19 ) The method of  claim 15 , wherein said heat-resistant fabric layer has an LOI of at least 45. 
     
     
         20 ) The method of  claim 15 , wherein said heat-resistant fabric layer has an LOI of at least 55. 
     
     
         21 ) The method of  claim 15 , wherein said heat-resistant fabric layer comprises Oxidized Polyacrylonitrile (OPAN). 
     
     
         22 ) A method of reducing the thermal image of a firearm suppressor, said method comprising attaching a cover to the firearm suppressor prior to use of the firearm, said cover comprising a heat-resistant fabric layer and a metal layer. 
     
     
         23 ) The method of  claim 22 , wherein said metal layer comprises aluminum. 
     
     
         24 ) The method of  claim 22 , wherein said heat-resistant fabric layer has an LOI of at least 25. 
     
     
         25 ) The method of  claim 22 , wherein said heat-resistant fabric layer has an LOI of at least 35. 
     
     
         26 ) The method of  claim 22 , wherein said heat-resistant fabric layer has an LOI of at least 45. 
     
     
         27 ) The method of  claim 22 , wherein said heat-resistant fabric layer has an LOI of at least 55. 
     
     
         28 ) The method of  claim 22 , wherein said heat-resistant fabric layer comprises Oxidized Polyacrylonitrile (OPAN).
