extending from the proximal end portion to the distal end portion, each of the one or more airflow channels being more proximal in the upper portion of the body than in the lower portion of the body. ### Claim 7 (depends on 3) The cover of claim 3, wherein, when the body houses the barrel, the one or more intake ports are disposed below the barrel, and, when the body houses the barrel, the one or more exhaust ports are disposed above the barrel. ### Claim 8 (depends on 1) The cover of claim 1, wherein the one or more sights have left and right laterally outer edges and a lateral length that extends from the left laterally outer edge to the right laterally outer edge, and the one or more exhaust ports are laterally spaced apart from the lateral outer edges of the one or more sights by a distance that is at least 10% of the lateral length of the one or more sights. ### Claim 9 (depends on 1) The cover of claim 1, wherein the body comprises: a base having an upper portion and a lower portion with the one or more intake ports disposed in the lower portion of the base; a top coupled to the upper portion of the base; and an intermediate cap disposed between the base and the top. ### Claim 10 (depends on 1) The cover of claim 1, further comprising one or more insulation layers coupled to the upper portion of the body. ### Claim 11 (depends on 1) The cover of claim 1, further comprising one or more insulation layers coupled to the upper portion of the body, wherein the upper portion of the body has a recess that is sized and dimensioned to receive at least one of the one or more insulation layers. ### Claim 12 (depends on 1) The cover of claim 1, wherein the body has a proximal end portion and a distal end portion, each of the proximal and distal end portions has a hole that is sized and dimensioned to receive the barrel. ### Claim 13 (depends on 1) The cover of claim 1, wherein the upper portion of the body has an outwardly extending flange that defines left and right laterally outer edges of the upper portion of the body that define the one or more exhaust ports. ### Claim 14 A cover for a barrel of a firearm, comprising: a cover body that is sized and dimensioned to cover at least an upper portion of a barrel of a firearm having one or more sights, the body having a longitudinal axis and a lateral axis, the body having an upper portion, the body being coupleable to the firearm below the one or more sights, the body having one or more exhaust ports that are disposed in the upper portion of the body and that are laterally spaced apart from the

through an interior of the cover body, wherein the upper portion of the body has left and right laterally outer edges and one or more upward bends in one or more of the left and right laterally outer edges, the one or more upward bends at least partially defining at least one of the one or more exhaust ports and extending inward from the one or more of the left and right laterally outer edges in a direction that is transverse to the longitudinal and lateral axes of the body. ### Claim 18 A cover for a barrel of a firearm, comprising: a cover body that is sized and dimensioned to house a barrel
