Mirage problems are best dealt with by using mirage bands that leads the barrel heat away from your line of sight, and not by containing it with wraps of different kinds.
Heat from the barrel and suppressor causes mirage, which distorts your field of view.
Using a Mirage band will allow you to channel that heat away from your line of sight.
