Ruger AR-556 MPR 223 Rem 18" Barrel 30+1 Capacity Multi-Purpose Rifle

The Ruger AR-556 MPR delivers precision and versatility in a multi-purpose rifle platform engineered for competitive shooting and tactical applications. This rifle combines enhanced accuracy features with proven AR-15 reliability in a configuration optimized for both close-quarters and extended-range engagements.

What Makes This Different

The MPR (Multi-Purpose Rifle) variant features an 18-inch 4140 chrome-moly steel barrel that provides superior accuracy over standard 16-inch carbine configurations. The Elite 452 two-stage trigger system delivers a crisp break with reduced pull weight compared to standard mil-spec triggers. Hard coat anodized 7075-T6 aluminum construction ensures corrosion resistance and structural integrity under demanding conditions.

Key Features

• 18-inch 4140 chrome-moly steel barrel with 1:8 twist rate for optimal bullet stabilization
• Elite 452 two-stage trigger system for enhanced accuracy and control

The 18-inch barrel length provides increased muzzle velocity and improved ballistic performance at extended ranges while maintaining maneuverability in confined spaces. The rifle excels in competitive shooting disciplines, varmint hunting, and designated marksman applications where accuracy takes precedence. The two-stage trigger system reduces shooter fatigue during extended shooting sessions and enables more precise shot placement.
