Ruger® SR-556™ Semiautomatic Rifle

Experience the rugged reliability Ruger is renowned for in a new rifle that redefines the AR platform. Its chrome-plated, two-stage, piston-driven operating system offers improved dependability over gas-driven rifles. A four-position, chrome-plated gas regulator allows the shooter to tune the rifle to specific ammunition or conditions. The bolt, bolt carrier and extractor are also chrome-plated to enhance performance and durability. A cold hammer-forged, chrome- lined, mil-spec 41V45 barrel delivers consistent accuracy. Troy Industries folding battle sights are adjustable and co- witness with mil-spec optics so they can easily be removed to make room for high-powered scopes. The Troy Industries quad-rail handguard provides a rigid mount for the piston-driven transfer rod. Rail covers for unused rails make for a more comfortable hold. A six-position, telescoping M4-style buttstock can be used to adjust length of pull. Includes two 30-round MAGPUL PMAG magazines and a soft-sided carry case.
