         12 . The barrel cooler of  claim 11 , further comprising a pair of retention knobs, each configured to secure to an aperture of the pair of apertures at a side of winged flange opposite the battery tubes. 
     
     
         13 . The barrel cooler of  claim 11  wherein the fan assembly comprises a housing and the battery tubes are connected to and extend away from the housing, and wherein the battery assembly is secured to the bottom of the first shroud with a lower portion of the first sidewall of the first shroud received within the first cradle. 
     
     
         14 . The barrel cooler of  claim 11 , further comprising a second winged flange, the second winged flange comprising a second cradle configured to receive an upper portion of the first sidewall of the first shroud, the second winged flange comprising a pair of apertures, each aperture of the pair of apertures configured to receive a battery tube of the pair of battery tubes. 
     
     
         15 . The barrel cooler of  claim 11 , wherein the fan assembly comprises a housing, the housing having a third cradle configured to receive a lower portion of the first sidewall of the first shroud, wherein the second winged flange is secured to the first shroud at a position above the fan assembly and on an opposite side of the first shroud from the fan assembly. 
     
     
         16 . The barrel cooler of  claim 1 , further comprising a transition cone positioned within the second shroud, the transition cone configured to coaxially receive an end of a barrel and comprising a conical surface angled away from the barrel. 
     
     
         17 . The barrel cooler of  claim 16 , wherein the transition cone configured to abut a suppressor connected to the end of the barrel. 
     
     
         18 . The barrel cooler of  claim 17 , wherein the transition cone is connected to a washer, the washer configured to fit over a threaded end of a barrel and configured to engage a shoulder at the threaded end of the barrel.
