Ruger AR-556 8502 State Compliant 5.56 NATO 16.1" Heavy Barrel

The Ruger AR-556 Model 8502 delivers proven reliability in a state-compliant configuration, featuring precision-engineered components for consistent performance. This semi-automatic rifle combines Ruger's manufacturing expertise with modern AR-15 platform benefits. Built to exceed military specifications while maintaining compliance with restrictive state regulations.

What Makes This Different

The heavy contour barrel profile provides enhanced accuracy and heat dissipation compared to standard pencil barrels. Ruger's proprietary bolt carrier group undergoes magnetic particle inspection for structural integrity. The 7075-T6 aluminum receivers offer 50% greater strength than standard 6061 aluminum while maintaining the same weight profile.
