Rock River Arms AR0784 LAR-15M NM A4 Complete Upper, 223 Wylde 20" Stainless Heavy Match Barrel, Black Rec/12.50" M-LOK Handgaurd, Railed Gas Block, A2 Flash Hider

The Rock River Arms AR0784 LAR-15M NM A4 Complete Upper represents a purpose-built platform for precision rifle enthusiasts, competitive shooters, and law enforcement marksmen who demand match-grade accuracy without compromise. This complete upper assembly eliminates the guesswork of component sourcing by pairing a professional-grade barrel with a cohesive system designed from the factory for sub-MOA performance. Whether you're building a dedicated National Match rifle or upgrading an existing lower receiver, this upper delivers the accuracy foundation that separates consistent hits from missed opportunities downrange.

The 20-inch stainless steel heavy match barrel chambered in .223 Wylde provides the thermal stability and harmonic consistency required for precision shooting, while the heavy profile minimizes barrel whip and shot-to-shot vertical stringing. The railed gas block allows for mounting backup iron sights or optics without rail conflicts, and the A2 flash hider manages muzzle blast effectively in both indoor and outdoor environments. The 12.50-inch M-LOK handguard offers modern modularity for mounting accessories—lights, lasers, or vertical grips—while maintaining a clean profile that won't interfere with competitive or tactical shooting positions. At 8.6 pounds, the upper balances substantial barrel mass with manageable weight, critical for shooters running extended practice sessions or competition events where fatigue degrades accuracy.

This complete upper pairs seamlessly with any AR-15 lower receiver, making it ideal for builders who already own compatible platforms or prefer to source lowers separately. Competitive shooters, precision rifle clubs, and law enforcement agencies running National Match or 3-gun programs will benefit from the factory-matched accuracy potential without the time investment of individual component vetting. Installation requires only standard AR-15 assembly knowledge—bolt carrier group, charging handle, and lower receiver attachment—making it accessible to experienced builders while delivering performance typically reserved for custom gunsmiths.
