Great Lakes Firearms 5.56 NATO 16" 31-Round Stainless Carbine

The Great Lakes Firearms 5.56 NATO 16" 31-Round Stainless Carbine delivers reliable, mission-ready performance for tactical operators, military personnel, and serious sport shooters who demand precision and durability. This carbine is purpose-built for close-quarters engagement, vehicle operations, and dynamic tactical scenarios where a compact platform with full rifle capability is non-negotiable. The 16-inch barrel strikes the critical balance between velocity, handling, and compliance, while the 31-round capacity ensures sustained fire capability without frequent magazine changes in high-stress environments.

Built from stainless steel, this carbine resists corrosion and environmental degradation—essential for field operations in salt spray, humid climates, and wet conditions where standard finishes degrade rapidly. The 5.56 NATO chamber delivers superior ballistics compared to .223 Remington, with higher pressure tolerance and consistent energy downrange, critical for barrier penetration and engagement beyond 100 meters. At 10 pounds, the platform maintains manageable recoil impulse and natural point-of-aim for rapid follow-up shots, while the compact 41.9-inch overall length enables seamless transitions through doorways, vehicles, and tight tactical spaces where full-length rifles create liability.

Law enforcement tactical teams, military units, and armed civilians benefit most from this carbine's proven ergonomics and rail-ready construction for optics, lights, and vertical grips. The stainless construction outlasts nitride or phosphate finishes in demanding environments, reducing long-term maintenance costs and ensuring reliability during critical moments. Standard AR-15 platform compatibility means operators can integrate proven accessories, calibrated optics, and sling systems already in inventory, minimizing training overhead and logistics complexity.
