The Maxim Defense MD15 L is a 5.56 NATO AR-15 built for shooters who want a modern, no-nonsense rifle without unnecessary complications. This is a purpose-built platform that delivers the reliability and accuracy you expect from a quality AR-pattern rifle, configured right out of the box for patrol, sport shooting, and general duty use. At 16 inches of fluted barrel and 33 inches overall length, it strikes a practical balance between maneuverability and velocity—short enough to handle in tight spaces, long enough to deliver 5.56 performance downrange.
The MD15 L features Maxim Defense's free-floating Slimline handguard with full M-LOK compatibility, giving you a clean, monolithic-style upper receiver platform that accepts standard AR accessories without proprietary nonsense. The FDE receiver pairs with black Magpul MOE furniture and a Magpul SL-K stock for a cohesive, functional aesthetic. You also get MBUS backup sights and a Blackout Defense flat trigger out of the box—genuine quality components, not bargain-bin compromises. The 30+1 capacity and standard 1/2x28 barrel thread pitch mean you're working with conventional AR logistics and aftermarket options.
Built from 7075 and 6061 aluminum with nitride finish and Type III anodizing, this rifle is engineered to handle field use without fussing over cosmetics. At 6 lbs 6 oz, it's a reasonably light handler without feeling cheap. Whether you're training at the range, building patrol readiness, or just want a straightforward 5.56 that works, the MD15 L delivers professional-grade capability at a rational price point.
