Product Overview
The Ruger AR-556 MPR (Multi-Purpose Rifle) in 5.56mm NATO is engineered for consistent performance across a spectrum of operational demands. This rifle configuration is designed with core components that optimize accuracy and operational reliability, making it suitable for discerning firearm enthusiasts and competitive applications.
Key Features
Precision Barrel and Gas System
The AR-556 MPR incorporates an 18-inch cold hammer-forged barrel with a 1:8″ right-hand twist rate. This specification is optimized for stabilizing a comprehensive range of 5.56mm bullet weights, directly contributing to consistent downrange accuracy. A mid-length gas system is integrated, providing a more balanced operating pressure curve. This design choice mitigates felt recoil impulse and enhances the overall operational reliability of the platform compared to carbine-length systems.
Robust Receiver and Accessory Integration
Constructed from forged 7075-T6 aluminum, both the upper and lower receivers provide a high-strength, durable foundation for the rifle’s operating components. A free-float M-LOK handguard extends the full length of the gas system, isolating barrel harmonics and ensuring repeatable accuracy. This handguard offers versatile attachment points for essential tactical accessories, including optics, illumination devices, and grip enhancements, without impacting barrel performance.
Enhanced Trigger Group
The rifle is equipped with the Ruger Elite 452 AR-Trigger. This two-stage trigger system delivers a clean, crisp break, facilitating precise shot placement and control critical for accuracy-focused engagements. The trigger’s consistent pull characteristics enhance user interface and contribute to repeatable performance.
