Maxim Defense MD15 Duty 5.56 NATO 16" Semi-Auto Rifle

The Maxim Defense MD15 Duty is a mission-ready 5.56 NATO semi-automatic AR-15 platform rifle built for duty, defensive, and hard-use applications. Designed around a black anodized aluminum receiver with an integrated Picatinny rail and MIL-SPEC internals, the MD15 Duty delivers the rugged reliability and out-of-the-box capability that modern shooters demand.

At the front of the rifle sits a 16" black nitride threaded barrel paired with an M-LOK handguard, giving you a versatile, modular shooting platform ready for lights, lasers, or other accessories. The muzzle is fitted with a classic A2 flash hider, and the threaded barrel allows easy upgrades to your preferred muzzle device or suppressor. The full-length Picatinny top rail accepts any standard red dot, holographic, or magnified optic, and the rifle ships with no iron sights installed so you can configure your preferred aiming setup.

Internally, the MD15 Duty is equipped with an ALG Combat trigger for a clean, consistent break. The furniture includes the popular B5 Bravo black polymer stock with multiple sling mounting points and a black polymer pistol grip. Overall length measures 33" with an unloaded weight of approximately 6.07 lbs, making it a well-balanced carbine suitable for duty use, training, or home defense.

Whether you are stepping into a duty rifle, upgrading a patrol carbine, or putting together a hard-use home defense build, the Maxim Defense MD15 Duty offers a complete, purpose-driven package with a clean blacked-out aesthetic and the durability the brand is known for.
