Black refers to a common color or finish used on firearm parts and accessories, achieved through anodizing, coating, or painting processes. It offers a sleek, tactical appearance and can enhance corrosion resistance and durability. Black finishes are available on a wide range of parts, including AR-15/AR-10 receivers, barrels, handguards, stocks, grips, magazines, muzzle devices, and small components. Compatible with all standard firearm platforms, black parts are popular for custom builds, tactical applications, and those seeking a classic, non-reflective look.
