You may have seen photos of them in different combat environments. Multicam cloth wrapped around a suppressor. In most cases these are suppressor covers. There is a lot of confusion when it comes to suppressor covers and their intended purposes. A suppressor cover is a heat-resistant material that covers the suppressor, often it is made of fiberglass or some other material rated for very high temperatures. Over these many have an additional camouflage sleeve in to help hide the cover itself. There are of-course variations throughout the industry.

Pros of the Suppressor Cover
Suppressors get hot. Really hot, many sources state around 7 degrees Fahrenheit per shot fired for 5.56×45.

A well made suppressor cover can help get rid of that heat mirage for more shots.
