The TAB Gear SAS3 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 is a fully enclosed tube of protective material. This cover must be installed with the label to the rear, toward the shooter. This cover was designed to make a smaller more compact model than the SAS1 yet still be able to effortlessly slide the cover off of the can onto the barrel to allow the can to cool in between shot strings, as well as being very easy to install back onto the can when shooting begins again.
