American Tactical Inc MILSPORT 5.56 NATO 13" 61-Round Carbine

The American Tactical Inc MILSPORT 5.56 NATO 13" 61-Round Carbine represents a purpose-built platform for shooters who demand compact handling without sacrificing firepower. Designed for law enforcement, military training, and tactical applications where barrel length and maneuverability are critical, this rifle bridges the gap between duty-grade performance and practical field ergonomics. The 13-inch barrel delivers rifle-velocity ballistics in a profile short enough for vehicle operations, breaching, and close-quarters scenarios while maintaining effective range for standard 5.56 NATO ammunition.

Built on proven direct impingement operating principles, the MILSPORT carbine cycles 5.56 NATO reliably across environmental extremes common in tactical deployments. The 61-round capacity designation indicates the magazine system's design compatibility with extended-capacity configurations, allowing operators to reduce reload frequency during sustained engagements or training cycles. A 13-inch barrel on a 5.56 platform generates approximately 2,400–2,500 feet per second with standard full-power loads, maintaining combat-effective velocity out to 300 meters while generating a notably higher report due to reduced powder burn time—a characteristic requiring hearing protection in operational environments.

Law enforcement tactical teams, military support personnel, and civilian shooters engaged in carbine training will find this platform well-suited for duty or competition use. The compact footprint excels in vehicle loadout configurations and confined-space operations while retaining standard AR-platform modularity for optics, lights, and accessory mounting. At approximately 1 pound, the rifle's weight distribution supports extended carry without fatigue, critical for operators who must maintain performance across multi-hour engagements or training evolutions.
