Maxim Defense Mdx 516 5.56 16" 30-Round Cerakote Rifle

The Maxim Defense MDX 516 5.56 16" 30-Round Cerakote Rifle represents a modern compact platform purpose-built for operators, law enforcement, and civilian users who demand reliability in confined spaces without sacrificing firepower. This rifle bridges the gap between carbine versatility and short-barreled rifle (SBR) performance, making it ideal for close-quarters combat training, home defense, and tactical operations where maneuverability takes priority. The 16-inch barrel configuration delivers the velocity needed for effective 5.56 NATO ballistics while maintaining a profile that excels in vehicle operations, building clearance, and dynamic shooting scenarios.

Maxim Defense engineered the MDX platform around a piston-driven system that cycles reliably across a broad spectrum of ammunition without the gas tube fouling common to direct-impingement designs—a critical advantage in rapid-fire training and sustained operations. The Cerakote finish provides superior corrosion resistance and durability compared to standard Parkerizing or anodizing, withstanding harsh environments, salt exposure, and repeated cleaning cycles that wear down lesser finishes. The 30-round capacity pairs seamlessly with standard STANAG magazines, ensuring compatibility with existing supply chains and giving shooters sustained fire capability for tactical and training applications without reloading.

Tactical professionals, law enforcement agencies upgrading duty rifles, and serious civilian operators benefit most from the MDX 516's ergonomic layout and combat-proven design philosophy. The rifle accepts standard AR-15 upper receiver components and is compatible with modern rail systems, optics mounts, and tactical accessories, allowing field customization for specific mission requirements. Whether configured for close-quarters work, designated marksman roles, or general-purpose engagement, the Maxim Defense MDX 516 delivers the accuracy, durability, and operating system reliability that separates purpose-built equipment from standard inventory.
