The Maxim Defense MD:15L is a lightweight, precision‑oriented AR‑15 rifle built for performance and adaptability. Chambered in calibers including 5.56 NATO, .223 Remington, and 6mm ARC, it features a free‑floating, spiral‑fluted barrel (16" or 18" options) designed to reduce weight and improve heat dissipation. Built with high‑grade 7075 and 6061 aluminum, the receiver assembly is finished in durable Cerakote over Type III hard‑coat anodizing. It sports a match‑grade trigger (such as the 3 lb Zero™ trigger), ambidextrous charging handle, and a 15″ M‑Slot/M‑Rax compatible handguard to accommodate suppressed or tactical setups. The MD15L balances rugged durability with modularity—Magpul stocks, backup MBUS sights, and standard A2 flash hiders come standard. With an overall length around 33–34.5″ and unloaded weight near 6.4–6.9 lbs, it serves as a dependable platform for both range enthusiasts and field applications.
