What Makes the Rock River Arms Forged A2 Stripped Upper Receiver Stand Out?

The Rock River Arms Forged A2 Stripped Upper Receiver is a cornerstone for building or upgrading an AR-15, especially for those seeking a classic, military-style aesthetic. Rock River Arms is known for quality components, and this stripped upper receiver provides a solid foundation for a reliable and accurate rifle. The A2 configuration, with its fixed carry handle and integrated rear sight, is a nod to the classic AR-15 designs that many shooters appreciate, and this receiver offers a blend of that traditional look with modern manufacturing precision.

My initial impression upon unboxing the Rock River Arms Forged A2 Stripped Upper Receiver was one of solid quality. The forging was clean, the anodizing was uniform, and the overall feel was sturdy.

Real-World Testing: Putting Rock River Arms Forged A2 Stripped Upper Receiver to the Test

First Use Experience

I tested the Rock River Arms Forged A2 Stripped Upper Receiver at my local outdoor shooting range. The build went smoothly and I was eager to see how it performed.

The conditions were sunny but slightly windy. I wanted to see how the integrated A2 sights performed in different lighting and wind conditions.

The upper was easy to mate with my lower receiver and all parts installed without issue. No special tools were needed beyond standard AR-15 armorer’s tools.

The only minor surprise was that I needed to adjust the rear sight slightly more than I anticipated for my preferred zero, but this is common. I soon had everything dialed in for accurate shooting.

Extended Use & Reliability

After several months of regular use, the Rock River Arms Forged A2 Stripped Upper Receiver has held up exceptionally well. I have put several hundred rounds through the rifle, and the upper receiver shows no signs of significant wear or loosening.

The anodized finish remains durable with no scratches or wear marks beyond what I would consider standard use. The rear sight has retained its zero and the overall assembly feels as solid as the first day.

Cleaning is straightforward using standard AR-15 cleaning procedures and solvents. The finish wipes down easily and the internal surfaces are accessible for proper maintenance.

Compared to some cheaper upper receivers I’ve used in the past, the Rock River Arms offering inspires confidence in its build quality. It is clearly a step above in terms of material and craftsmanship.
