Bushmaster M4 Patrolman's 5.56 NATO 16" 31-Round Threaded Barrel Carbine

The Bushmaster M4 Patrolman's 5.56 NATO 16" 31-Round Threaded Barrel Carbine is a law enforcement and tactical operator's choice for patrol rifle duties, home defense, and professional security applications. Purpose-built for agencies and armed professionals who demand a dependable, modular platform, this carbine combines proven M4 ergonomics with practical features that support real-world deployment. At 9.2 lbs and 41.2 inches overall length, it delivers maneuverability in tight quarters while maintaining the ballistic capability of the 5.56 NATO cartridge.

The 16-inch threaded barrel provides a velocity sweet spot for 5.56 ammunition—typically 2,800–2,950 fps with standard loads—while the threads accept common muzzle devices such as flash hiders, suppressors, or compensators, allowing shooters to tailor performance to operational requirements. The 31-round magazine capacity ensures sustained firepower during extended engagements or training evolutions, a proven standard across military and law enforcement units. The M4 platform's modular design—Picatinny rail-ready and compatible with AR-15 accessories—enables rapid optic mounting, foregrip installation, and tactical light integration without gunsmithing.

Patrol officers, SWAT teams, security contractors, and civilian tactical enthusiasts favor this carbine for its reliability, accuracy, and ease of maintenance in the field. The compact 16-inch profile and flat-top receiver design work seamlessly with standard AR-15 furniture, allowing immediate upgrades or repairs using readily available components. Whether mounted in a patrol vehicle, staged for rapid deployment, or configured for precision rifle courses, the Bushmaster M4 Patrolman's delivers the consistency and ergonomic familiarity that trained shooters expect from a combat-tested platform.
