Windham Src Upper 556 16" Ft Blk

The Windham SRC Upper 556 16" FT Black is a purpose-built upper receiver assembly engineered for AR-15 platform shooters who demand modular flexibility and consistent performance. Designed as a complete upper assembly, this component delivers the ballistic efficiency of an intermediate cartridge in a configuration optimized for tactical carbine shooting and law enforcement patrol.

At 5.69 lbs and measuring 6.37 x 6.63 x 32 inches, the Windham SRC upper strikes a practical balance between maneuverability in confined spaces and sight radius for accurate target engagement. The 16-inch barrel length on this upper receiver represents the performance sweet spot for 5.56mm NATO/.223 Remington cartridges, delivering velocity sufficient for combat-effective range and standard magazine compatibility across the AR ecosystem.

This configuration is widely adopted by military units, law enforcement agencies, and serious civilian shooters. The flat-top receiver design accommodates standard Picatinny rail mounted optics, providing shooters with true mechanical zero on their preferred sighting systems. This upper is suited for operators building a complete rifle, upgrading an existing platform, or staging a quality spare upper for duty rotation.
