Bushmaster 0010011BLK M4 5.56 NATO 16" 31-Round Carbine

The Bushmaster M4 5.56 NATO 16" 31-round carbine represents a proven platform trusted by law enforcement and military units for nearly two decades. Purpose-built for intermediate-distance engagement and dynamic tactical operations, this semi-automatic rifle delivers reliability in demanding field conditions. The 16-inch barrel balances velocity retention with maneuverability, making it equally effective for patrol carbine applications, home defense, or training scenarios where modularity and accuracy matter.

Bushmaster's flat-top receiver design accommodates standard Picatinny rails for optic mounting, enabling rapid sight picture transitions and accessory customization without gunsmithing. The direct impingement system cycles reliably across a wide range of ammunition types, while the 31-round magazine capacity maximizes engagement time without frequent reloads—critical in high-stress situations. At 8.8 lbs unloaded, this carbine maintains controllability during extended shooting sessions, and its 41.3-inch overall length permits vehicle transport and close-quarters movement without sacrificing barrel dwell time for consistent velocity.

This rifle excels for shooters seeking a versatile, battle-tested platform without premium pricing. Law enforcement agencies and civilian operators rely on this exact configuration for duty rifle applications, competition preparation, and skill development. The modular M4 platform ensures compatibility with a vast ecosystem of handguards, stocks, triggers, and charging handles, allowing shooters to tailor ergonomics and performance to their specific mission requirements. Brass-cased 5.56 NATO ammunition is readily available and cost-effective, supporting frequent training cycles essential for proficiency maintenance.
