The Christensen Arms CA-15 Duty is a purpose-built, duty-grade AR-platform rifle chambered in the versatile .223 Wylde, engineered to deliver exceptional reliability, accuracy, and feature-rich performance for law enforcement, home defense, and serious sporting applications. Built around a 16-inch stainless steel barrel with a 1:8 twist rate and a mid-length gas system, this rifle delivers a softer, more controllable recoil impulse and improved reliability across a wide range of ammunition compared to carbine-length gas systems. The Lancer handguard provides a rigid, lightweight platform for accessory mounting, while the Magpul adjustable stock delivers a comfortable, customizable fit for shooters of all sizes. Finished in a durable black anodized coating throughout, the CA-15 Duty is a no-compromise modern sporting rifle built to Christensen Arms' exacting standards of quality and performance.
