Just about every suppressor on the market will do an admirable job of reducing muzzle flash, and there are even a few that are specifically designed to excel at this. However, it’s important to keep in mind that reductions in muzzle flash can come with trade-offs, such as increased weight or length, and/or decreased sound reduction.
When shopping for a suppressor, those looking specifically for reduced muzzle flash should focus on models that use ablative materials. These materials work by disintegrating when they come into contact with hot gases, which effectively cools down the gases before they exit the muzzle. This results in a significant reduction in muzzle flash. Ablative materials also have the added benefit of not significantly affecting sound reduction levels
