Ruger AR-556 MPR Features
Built with forged 7075-T6 aluminum receivers and finished in a black hard-coat anodizing, the AR-556 MPR offers a strong, corrosion-resistant foundation. The cold hammer-forged 4140 chrome-moly steel barrel is nitride-treated and threaded with a 1/2″-28 pitch, capped with a Ruger muzzle brake to reduce recoil and muzzle rise. A 1:8″ twist rate supports a wide range of bullet weights for reliable accuracy in varied shooting applications.
The 15-inch free-float M-LOK handguard offers exceptional rigidity while maintaining a lightweight feel and expanded modularity for mounting AR-15 accessories. The rifle is outfitted with Magpul MOE SL stock and a Magpul MOE grip, offering a comfortable and AR-15 Adjustable platform to accommodate different body types and shooting styles. The Ruger Elite 452 AR trigger delivers a clean, crisp 4.5-pound two-stage pull with a fast lock time—enhancing shooter precision. This model includes one 10-round magazine, making it compliant for more restrictive jurisdictions.
