Description
The One Horse OH-CU02 Complete Upper Receiver (MPN: OH-CU02) is a compact 5.56 NATO AR-15 upper built around a 10.5-inch barrel, 10-inch M-LOK handguard, nitride-finished bolt carrier group, and included charging handle. Rather than requiring the buyer to source the major upper components separately, the OH-CU02 arrives as a complete assembly ready to pair with an appropriate Mil-Spec AR-15 lower receiver.
One Horse specifies a 4150 steel barrel with a medium profile, 1:7 twist, pistol-length gas system, and 1/2x28 muzzle threads. The 10-inch M-LOK rail provides accessory mounting space while maintaining a compact overall package. The included nitride BCG is intended to provide a durable, low-maintenance operating surface, and a standard charging handle is supplied with the upper. One Horse lists the assembly as made in the USA.
Key Features & Compatibility
- 10.5-Inch 5.56 NATO Barrel: Compact configuration with 1:7 twist for common 5.56/.223 projectile weights.
- 10-Inch M-LOK Handguard: Lightweight accessory-ready rail system.

The OH-CU02 is a strong fit for a compact 5.56 build where a complete upper assembly is preferred over sourcing the barrel, BCG, rail, and charging handle individually. Shop .223 Remington and 5.56 NATO ammunition at Recoil Gunworks.
