Global Ordnance Monolithic 5.56 NATO 16" AR-15 M-LOK Rifle

The Global Ordnance Monolithic 5.56 NATO rifle delivers precision shooting capabilities with its integrated upper receiver design and 16-inch barrel configuration. This platform eliminates the traditional barrel nut connection point, creating a stronger foundation for consistent accuracy across multiple shooting disciplines.

What Makes This Different

The monolithic upper receiver construction sets this rifle apart from standard AR-15 platforms by machining the rail system and receiver from a single piece of aluminum. This eliminates potential flex points that can affect accuracy, while the continuous top rail provides 20+ MOA of mounting space without height variations. The M-LOK handguard system offers direct attachment points every 45 degrees around the circumference, reducing weight compared to traditional quad-rail designs.

Key Features

• Monolithic upper receiver with integrated rail system for enhanced rigidity
• 16-inch chrome moly vanadium steel barrel with 1:7 twist rate
• M-LOK compatible handguard with multiple attachment points
• Modular black stock with adjustable length of pull
• Ergonomic black polymer pistol grip with textured surface
• Standard AR-15 trigger group compatibility
• Mil-spec charging handle and bolt carrier group

Field performance centers on the rifle's ability to maintain zero through temperature changes and extended firing sessions. The monolithic design reduces thermal expansion differences between components, while the 16-inch barrel provides optimal velocity for 5.56 NATO ammunition without excessive muzzle blast. Competition shooters benefit from the rigid platform's consistency, while the M-LOK system allows rapid accessory changes between stages.
