Keep your SureFire suppressor adapter clean with the Adapter Carbon Scraper Tool (ACST). This handy accessory is compatible with the majority of SureFire's muzzle brakes, flash hiders, and WARCOMPS. The ACST is easy to use, simply place is over the suppressor adapter and rotate clockwise and counter clockwise to remove carbon fouling. While carbon may still be visible on the adapter, this is not a concern as the ACST is designed to ensure that correct tolerances are kept for precise suppressor fitment. The ACST itself requires little maintenance and can either be wiped or blown with compressed air to clean the inside of the tool. Stainless steel construction and a nitride prevent corrosion. Cut your field cleaning time with a SureFire ACST.
