The TAB Gear SAS1 Suppressor Cover is designed to prevent mirage from obscuring your site picture after multiple shots. Eliminating mirage is accomplished by the use of insulating materials - your can heats up, but the SAS stays cool. The outer shell of the TAB SAS will not heat up so your equipment and person will not become damaged with accidental or intentional contact. Removal and handling of your can, while inside the TAB SAS, immediately after firing is possible due to the high quality insulating materials used in the construction. This model opens down the length of the suppressor and is held closed with a strip of Velcro. The cover must be installed with the label to the rear, toward the shooter.
