How to Clean a Chrome-lined Barrel

Chrome-lined barrels assist in preventing premature corrosion and wear in high-powered guns. Chrome-lined barrels were introduced by the military with the appearance of machine guns capable of wearing a barrel in as few as 1,000 rounds. Most damage is generated as the barrel heats when multiple rounds are fired. Normal cleaning methods won't damage the barrel and are effective in cleaning to maintain accuracy and safety.
