Our standard sport upper. This is a lightweight, accurate, and reliable upper, designed for sport use. For self-defense or mission-critical use, we recommend the Rifleman v1.0.0 upper.
Prior to shipping, all complete upper receivers are fully assembled, headspaced, and test fired. If purchased with a BCG, the BCG used for headspacing and test firing will be included.
The upper receiver group will show handling marks consistent with the listed quality control procedures.
All Grey Mesa Industries uppers and components are 100% made in the USA - no Chinese small parts.
