Ruger AR-556 5.56 NATO Semi-Auto Rifle 16.1" Barrel 30+1 Capacity

The Ruger AR-556 delivers proven AR-15 platform reliability with enhanced features that set it apart from basic entry-level rifles. This 5.56x45mm NATO chambered rifle combines Ruger's manufacturing expertise with practical upgrades that matter for serious shooters.

What Makes This Different

The AR-556 features a medium contour barrel profile that balances accuracy with manageable weight, unlike heavy barrel variants that add unnecessary bulk. The threaded muzzle accepts standard 1/2x28 muzzle devices, while the hard coat anodized finish provides superior corrosion resistance compared to basic phosphate coatings. Glass-filled nylon handguards offer better heat dissipation than standard polymer alternatives.

Key Features

• 16.1-inch threaded medium contour barrel with 1:8 twist rate for optimal bullet stabilization
• Hard coat anodized upper and lower receivers for enhanced durability and corrosion resistance
• Glass-filled nylon handguards with heat shields for improved thermal management
• Six-position collapsible stock adjusts from 10.25" to 13.5" length of pull
• Includes 30-round Magpul PMAG for reliable feeding
• Optics-ready flat-top upper receiver with full-length Picatinny rail
• Standard AR-15 trigger group and bolt carrier group for easy maintenance

Field performance centers on the rifle's 1:8 twist rate barrel, which stabilizes both 55-grain and heavier 77-grain projectiles effectively. The medium contour profile maintains accuracy during extended shooting sessions while keeping overall weight manageable for tactical applications. Weather-sealed components and quality control testing ensure reliable function in adverse conditions from competition ranges to duty environments.
