With sustained high rates of fire, sand, carbon, and brass fragments from case rims and primers, can all accumulate to form a heat-baked crud around the locking lug area. Solvents, brushes, mops, and lug picks can all do a fine job of removing this baked on crud….when there’s enough time and enough light to use them. But, the Talon lug cleaning tool, like its counterpart the CATM4 bolt and carrier tool, was designed to let the operator perform immediate action to keep the weapon running in the field. So, whether you’re on patrol, or on deck at a 3-Gun match, there’s probably time to take the Talon lug cleaning tool for a spin across your locking lugs. Just to be sure!
