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. The reason one might choose to have a suppressor cover can be one of many.

Pros of the Suppressor Cover

Heat mirage

Suppressors get hot. Really hot, many sources state around 7 degrees Fahrenheit per shot fired for 5.56×45. As these suppressors heat up they put off heat, these rising heatwaves can hinder one’s ability to make precision shots when looking through a magnified optic. A well made suppressor cover can help get rid of that heat mirage for more shots.

Hot suppressor

If you’re rocking a single or two point sling and you transition to your sidearm that rifle is going to swing down and make contact with your leg. Suppressors can be dangerously hot and have been known to burn holes in pants. You’re having a bad / good day if your suppressor is getting that hot. The cover also helps your buddies so that you don’t brand them during training in close quarters environments. In either case a suppressor cover helps protect you from the heat during transition

Thermal heat signature
