Ventilated Rib

The ventilated rib is designed to help cool and more particularly to direct the shimmering hot air that rises from hot barrels away from the line of sight in order to reduce mirage disturbance in the view of the target. Ventilated ribs are useful on target guns, but less desirable on field guns where small twigs and other detritus can become lodged in the openings under the rib.
