👉 A coated weapon is a type of firearm where the barrel, often the most critical part for accuracy and durability, is treated with a protective coating. This coating, typically made of materials like chrome nitride or titanium nitride, enhances the barrel's resistance to heat, corrosion, and wear, significantly improving its longevity and performance. The coating also helps reduce the rate of barrel degradation, maintaining consistent accuracy over time. This technology is especially beneficial in high-stress environments where rapid fire and precision are essential, such as in military or law enforcement applications.
