Rock River Arms LAR-15M Operator DMR 5.56 NATO 16" 30rd Black

The Rock River Arms LAR-15M Operator DMR delivers precision-focused performance in a battle-tested platform designed for demanding applications. This designated marksman rifle configuration combines match-grade components with tactical features that extend effective range beyond standard carbine capabilities. Built on Rock River Arms' proven LAR-15 platform, this rifle bridges the gap between close-quarters versatility and long-range accuracy.

What Makes This Different

The Operator DMR stands apart from standard AR-15 configurations through its precision-oriented component selection and enhanced ergonomics. The OEM match trigger provides a crisp, consistent break that reduces group sizes compared to standard mil-spec triggers. The 16-inch barrel length optimizes velocity retention while maintaining maneuverability, delivering superior ballistic performance over shorter carbine barrels without the bulk of full-length rifles.

Key Features

• OEM match trigger system for enhanced accuracy and consistent shot placement
• BCM SOPMOD stock with multiple length-of-pull positions and battery storage
• 13-inch M-LOK handguard providing 12 o'clock Picatinny rail and modular attachment points
• Hogue beavertail grip with finger grooves for improved control and comfort
• Magpul MBUS Pro steel flip-up backup iron sights with precision windage adjustment
• 16-inch chrome-moly steel barrel with 1:9 twist rate optimized for 55-77 grain projectiles
• Standard AR-15 magazine compatibility accepting all STANAG pattern magazines

The rifle excels in precision shooting applications where accuracy takes priority over rapid fire capability. Competition shooters benefit from the match trigger's consistent break and the stable shooting platform provided by the adjustable stock. Law enforcement and military personnel appreciate the extended effective range while retaining the familiar AR-15 manual of arms. The free-floating handguard eliminates barrel contact that can affect precision, while the M-LOK system accommodates bipods, lights, and other accessories without adding unnecessary weight.
