When it comes to home defense the Springfield Armory Saint is the ultimate AR-15 rifle to defend your legacy. Featuring a 16" chrome moly vanadium Melonite-finished barrel, chambered in .223 Rem./5.56 NATO with 1:8 twist with incredible accuracy. Built with a direct impingement midlength gas system for smooth shooting, less recoil, and reliability. Proprietary, enhanced micro polished, nickel boron coated, and a GI-style trigger group with a smooth and consistent trigger pull. The type-III, hard-anodized, corrosion-resistant, 7075 T6 aluminum upper and lower receiver maximize strength while remaining lightweight. The SAINT is optics-ready out of the box. The flat-top receiver is topped with Springfield Armory low profile flip-up dual aperture rear sight and up front, the A2-style gas block and front sight feature a standard post adjustable for elevation. Unlike most AR-15 rifles that leave the factory with standard mil-spec furniture, the SAINT includes meaningful upgrades across the board. The bottom line? When it’s time to protect and defend, trust the SAINT.
