The SR-556 offers Ruger's legendary rugged reliability and employs a patent-pending, chrome-plated, two-stage piston-driven operating system that provides the user with a cleaner, cooler-running, reliable firearm that is truly state-of-the-art. The chrome-lined gas block and chrome-plated piston and regulator work together to provide a smooth power delivery stroke to the bolt carrier, and the by-products of the gas system are vented out the bottom of the gas block, away from the bolt carrier, keeping the action clean and free from contaminants. This results in significantly improved performance over gas-driven rifles. The Ruger SR-556 features folding iron sights, a quad rail handguard providing four MIL-STD 1913 Picatinny rails, a manganese phosphate/hardcoat anodized finish, and three PMAG magazines.
