Field Characteristics

On the tactical side, the 16″ barrel provides a balance of muzzle velocity and maneuverability in close quarters. The single barrel type and polymer grip keep weight down for quicker transitions and sustained handling. The black finish is durable for routine duty use and hides wear in high-contact environments.

Caliber and applications

The 5.56 x 45 MM nato round is a versatile defensive cartridge with manageable recoil, wide ammunition availability, and excellent terminal and barrier performance when matched to modern bullet designs. For home defense, range training, and evolution into patrol duties, 5.56 remains a practical choice for follow-up shots and magazine capacity.

Practical considerations for owners

As a used rifle, inspect the barrel throat, bolt carrier group, and receiver extension for wear; these are common check points on semi-auto rifles. The standard 30-39 round magazine capacity gives extended engagement capability without frequent reloads, though local laws and mission profiles should guide magazine selection. Replacement parts and accessories are widely available given Armalite compatibility with standard AR components. View product details and pricing
