Maxim Defense MXM49734 MD15 L 5.56 NATO 16" 31-Round Rifle

The Maxim Defense MD15 5.56x45mm NATO rifle with 16-inch fluted barrel delivers law enforcement patrol reliability in a modular M-LOK platform. Built on Maxim's proven free-floating handguard architecture, this rifle combines accuracy and ergonomic flexibility—critical for officers requiring precision at variable distances without sacrificing quick target transitions. The 30-round capacity and Sniper Gray receiver paired with black Magpul furniture present a professional appearance across duty and training environments.

The 16-inch fluted barrel optimizes the 5.56 NATO cartridge for effective range and velocity while maintaining overall weapon length suitable for vehicle and building clearance operations. Free-floating barrel design reduces stress on the receiver, enhancing shot-group consistency during rapid-fire drills or sustained engagement. M-LOK compatibility across the handguard enables quick-attach mounting of tactical lights, lasers, and vertical grips without tools. MBUS iron sights provide backup aiming without battery dependency, while the Blackout Defense flat trigger delivers predictable reset for accurate shooting under stress. The SL-K stock allows length-of-pull adjustment for varying gear loads and shooter physiology.

Purpose-built for law enforcement patrol applications, the MD15 serves agencies seeking an intermediate-range platform balancing duty reliability with modern ergonomic standards. The modular design supports individual officer preference—whether adding thermal imaging, red-dot optics, or suppressor-ready configurations. At 9.2 pounds, the rifle sits in the operational weight range preferred by officers conducting extended patrols or tactical entries where fatigue management directly affects shot placement and situational awareness.

The 5.56x45mm NATO platform remains the standard intermediate cartridge for professional and civilian shooters, offering superior velocity and barrier penetration over pistol-caliber carbines while delivering controllable recoil for followup shots. Maxim's reputation for user-focused duty design emphasizes field reliability over unnecessary complexity—a philosophy evident in the MD15's straightforward controls and time-tested component selection.
