Springfield Armory ST916556B Saint AR 15 Semi-Auto .223 / 5.56 16″ 30+1 6-Position Hard Coat Anodized
Springfield ST916556B: The Saint is the ideal refinement of the time-tested AR-15 design and represents everything that a defensive carbine should be. It features extra-tough, forged aircraft-grade 7075 T6 aluminum upper and lower receivers joined using the Accu-Tite system and Type III hard coat anodized. A mid-length gas system paired with a heavy tungsten buffer, the Saint also has an M16 bolt carrier group machined from Carpenter 158 steel, shot peened and magnetic particle inspected. The 16″ Chrome Moly Vanadium barrel is treated with Melonite and has a 1:8″ twist rate for complete ammunition flexibility. The micro-polished trigger components are treated with Nickel Boron resulting in the feel of a competition trigger with the appropriate mil-spec pull weight for a defensive rifle. The Saint is optic-ready out of the box with a flat-top receiver topped with Springfield Armory’s low profile flip-up dual aperture rear sight with 1/2 MOA windage adjustment capability, and an A2-style gas block post front sight. The exclusive Bravo Pkmt handguard has an ultra modern two-piece slim contour design with heat shield and keymod attachment points. The Bravo 6-position buttstock is rattle-free with positive cheek weld areas, a rubber butt plate for traction, and one fixed and two QD sling attachment points. It is complemented by a Bravo Mod 3 pistol grip designed to improve defensive performance. This model includes one 30-round magazine.
