The Operator is Rock River's law enforcement carbine configuration — a 16-inch flat-top AR-15 with an enhanced trigger, rail handguard, and a feature set calibrated for patrol and tactical use. It was sold direct to law enforcement agencies and civilian buyers who wanted a duty-grade AR without the custom-shop wait time. The Operator name reflects its intended end-user rather than its design novelty. Type: Rifle Action: Semi-Automatic Caliber: 5.56 NATO Capacity: 30 Year introduced: 2006, USA Weight: 99.2 oz Overall length: 32" Status: Active Intended use: Law Enforcement, Tactical, Home Defense
