Colt Epr Upper 5.56 16" Mlok Blk

The Colt EPR Upper 5.56 16" M-LOK Black is a purpose-built AR-15 upper receiver assembly designed for reliability in demanding conditions. Manufactured by Colt's Manufacturing, this upper delivers the durability and precision Colt is known for among law enforcement, military, and serious civilian operators. The 16-inch barrel chambered in 5.56 NATO/.223 Rem provides an optimal balance of velocity, handling, and modularity for patrol, training, and operational use.

The M-LOK handguard system allows for quick attachment and removal of tactical accessories—optics mounts, lights, vertical grips, and rail systems—without tools or permanent modifications. This modular platform means the Colt EPR upper can be configured to match specific mission requirements, whether that's a minimalist setup for training or a fully outfitted combat configuration. At 4.69 lbs, the upper receiver assembly maintains a practical weight that doesn't compromise maneuverability or cause fatigue during extended operations. The 16-inch barrel length sits in the sweet spot for CQB-adjacent work and vehicle operations while maintaining adequate 5.56 velocity for target engagement beyond intermediate ranges.

This upper is built for operators who understand that consistency matters. Shooters running carbine courses, conducting qualification standards, or maintaining readiness for duty-specific roles rely on components that perform the same way every cycle. The Colt EPR upper fits that profile—it's not a budget option, and it's not over-engineered with unnecessary features. It's a straightforward, proven upper receiver that cycles reliably and holds zero through extended training blocks and real-world deployment scenarios. Compatible with standard AR-15 lower receivers and common accessories, the Colt EPR can be integrated into an existing platform or serve as the foundation for a new build.
