Many who use SureFire muzzle devices and suppressors have encountered issues with attaching and detaching due to carbon fouling. This Muzzle Device Cleaning Tool was created to remove carbon fouling from the corresponding SureFire suppressor adapter to an adequate level for proper suppressor attachment.
Simply place the ACST over the SureFire “Suppressor Adapter” and rotate clockwise and counter-clockwise until carbon fouling is removed. All of the carbon won’t necessarily be removed, but things will be in tolerance 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.
Available in 5.56 and 7.62 sizes.
