The Duty Series Rifles from Andro Corp Industries are purpose-built for shooters who demand uncompromising reliability and proven performance in high-stress, real-world environments. Originally built for law enforcement, the ACI-15 556 DUTY 16 and ACI-15 556 DUTY 10.3 are engineered to be true battle-ready platforms, featuring premium Ballistic Advantage Hanson barrels for exceptional accuracy and durability, M16 full-auto rated bolt carrier groups for flawless cycling, and robust forged receivers for maximum strength. Every critical component—from the corrosion-resistant QPQ barrel finish to the advanced Midwest Industries MLOK handguards and Breek Arms Warhammer ambidextrous charging handles—has been selected to meet or exceed the standards trusted by military, law enforcement, and serious civilian users.

What sets these Duty Series Rifles apart is their attention to detail and commitment to field-proven reliability. The 16-inch model offers optimal ballistic performance and controllability for patrol or perimeter defense, while the 10.3-inch pistol excels in close-quarters, vehicle, or confined space scenarios where maneuverability is paramount. Both models feature enhanced controls, ambidextrous selectors, and B5 Systems furniture for ergonomic handling under stress. The bolt carrier group—precision-machined, HP/MPI tested, and built to mil-spec—is the heart of each rifle, providing the rugged dependability required for sustained use and rapid fire. With a true lifetime warranty and American-made quality, these Duty Series Rifles are trusted by professionals and built for those who refuse to compromise on their gear.
