Key Features

What You Get

This is a complete upper receiver assembly, meaning it includes everything above the lower receiver. You'll need to source a compatible lower receiver to complete your rifle build. The included bolt carrier group and charging handle are factory-installed and ready to function.

Practical Considerations

The 18" barrel strikes a balance between velocity and maneuverability, making it suitable for both tactical applications and hunting. The M-LOK system allows you to mount optics, lights, and other accessories exactly where you need them. The nitride finish requires minimal maintenance while providing excellent protection against the elements.
