Colt EPR Upper 5.56 NATO 16" M-LOK Black – AR-15 Compatible

The Colt EPR (Enhanced Patrol Rifle) Upper Receiver chambered in 5.56 NATO is a complete drop-in assembly for mil-spec AR-15 lower receivers. This 16-inch configuration features an M-LOK handguard for direct accessory mounting without additional rail sections, combining Colt's factory precision with modern modularity for patrol, competition, or general-purpose use.

Constructed from 7075-T6 aluminum with a black anodized finish, this upper includes a chrome-lined barrel with a 1:7 twist rate optimized for stabilizing heavier projectiles. The flat-top receiver accepts any mil-spec charging handle and provides a full-length Picatinny rail for optics mounting. Installation requires only standard AR-15 takedown pins—no gunsmithing needed. This is a complete upper assembly ready to mate with your AR-15 lower receiver.
