SKU: SPKSTU5050-CQ2D
The Spike's Tactical 556 Upper 14.5" with Picatinny Rail and Dust Cover is a complete, ready-to-fire upper receiver assembly engineered for AR-platform rifles. This unit ships fully inspected, tested, and function-verified from Spike's manufacturing facility—drop-in capability that eliminates guesswork on critical assembly tolerances.
The 14.5-inch mid-length barrel delivers balanced velocity and handling characteristics suited to intermediate-distance shooting while maintaining maneuverability in confined spaces. A forged upper receiver paired with a phosphate M16-profile bolt carrier group provides proven durability across high-round-count applications. The integrated Picatinny rail system supports standard optics and accessory mounting without adapter plates. Weighing 4.56 lbs, this upper maintains a compact profile without sacrificing component rigidity.
This configuration is built for operators, law enforcement trainers, and precision shooters who require a vetted, field-ready upper without the time investment of sourcing and assembling individual components. The 556 platform balances 5.56 NATO reliability with proven accuracy standards. Spike's quality control process—including complete test-fire verification before shipment—addresses the primary concern when purchasing pre-assembled uppers: functional certainty from day one.
The mid-length gas system on a 14.5-inch platform provides a sweet spot for cycling reliability across a wide range of ammunition types and suppressed/unsuppressed configurations, making this upper versatile for duty cycles, training programs, and competition use.
