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

The Great Lakes Firearms 5.56 NATO 16" 31-Round Threaded Barrel Rifle delivers a modern, modular platform built for law enforcement, military personnel, and serious civilian shooters who demand reliability and adaptability. This mid-length rifle balances maneuverability with velocity, making it ideal for close-quarters engagement, patrol environments, and tactical training scenarios where compact handling without sacrificing ballistic performance is critical.

The 16-inch barrel optimizes the 5.56 NATO cartridge for velocities between 2,800–2,900 fps while maintaining a manageable overall length of 42 inches—essential for vehicle egress and confined-space operations. The threaded barrel accepts standard 1/2x28 muzzle devices, allowing users to integrate suppressors, flash hiders, or compensators to suit mission requirements and reduce controllability issues during rapid fire. At 10 pounds unloaded, the rifle remains light enough for extended patrol or tactical operations while providing inherent stability for accurate shot placement, and the 31-round capacity delivers sufficient firepower for dynamic scenarios without frequent reloads.

This platform benefits law enforcement units, military personnel, armed security teams, and trained civilians building a reliable duty or home-defense rifle. The modular AR-15 architecture ensures compatibility with aftermarket furniture, optics, and training accessories, allowing shooters to customize for specific operational demands. Proper maintenance and familiarity with 5.56 NATO ballistics and barrel heating during sustained fire ensure peak performance in high-stress environments.
