The flat-top receiver is 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 Magpul MOE 6-position buttstock has a rubber butt plate and one fixed and two QD sling attachment points. It is complemented by a Magpul MOE pistol grip designed to improve defensive performance.
