SUPPRESSOR COVER A suppressor cover is a protective sleeve that fits over the suppressor of a firearm. One of the benefits of using a suppressor cover is that it can help reduce the mirage effect that can occur when shooting at long distances. Mirage occurs when the heat generated by the suppressor causes the air around it to distort, creating a shimmering effect that can make it difficult to see the target. Using a suppressor cover made from high-temperature resistant materials can help prevent mirage while shooting at long distances. Mirage occurs when heat rising from the barrel distorts the view of the target, making it difficult to aim accurately. A suppressor cover can help to insulate the barrel and suppressor, reducing the amount of heat that escapes and minimizing mirage.
