Great Lakes Firearms 5.56 NATO 16" 31-Round Threaded Barrel Carbine

The Great Lakes Firearms 5.56 NATO 16" 31-Round Threaded Barrel Carbine is a modern sporting rifle engineered for tactical operators, competitive shooters, and serious rifle enthusiasts who demand reliability and modular versatility. Built on proven direct impingement architecture, this carbine bridges law enforcement duty requirements with civilian accessibility, offering the compact form factor and rapid-fire capability that professional shooters have relied on for decades. At 8.8 lbs, it strikes an ideal balance between control and maneuverability, making it suitable for both bench validation and dynamic tactical applications.

The 16-inch barrel delivers velocity and ballistic consistency across standard 5.56 NATO and .223 Remington ammunition while maintaining compliance with federal rifle length standards. The threaded muzzle—a critical detail for operators requiring sound signature reduction or recoil management—accepts industry-standard 1/2x28 muzzle devices, enabling rapid integration of suppressors, compensators, or flash hiders without permanent modification. This design philosophy reflects professional military doctrine: modular components allow field-level adaptation to mission requirements without the need for armorer-level intervention.

Law enforcement and military professionals recognize the value of tested, standard-pattern rifles for training continuity and spare parts interchangeability across duty teams. The 31-round magazine capacity ensures sustained suppressive fire capability, critical for both defensive scenarios and training drills where magazine changes introduce delay. This carbine integrates seamlessly with Picatinny rail systems, optic mounts, and tactical accessories that define modern rifle configurations, making it an excellent platform for precision work, home defense, or range mastery. Magazine compatibility extends to any standard AR-pattern 5.56 NATO receiver, giving shooters flexibility in ammunition feed system selection.
