DoubleStar DS-4 AR-15/M4 Flattop 16″ Upper Receiver Review

Let’s Dive into DoubleStar DS-4 AR-15/M4 Flattop 16″ Upper Receiver

The DoubleStar DS-4 AR-15/M4 Flattop 16″ Upper Receiver is designed to be a reliable and versatile option for AR-15 enthusiasts. DoubleStar is a reputable manufacturer, and this upper receiver boasts features like M4 feed ramps and a 1:9 twist rate, catering to a wide range of 5.56 NATO ammunition. It offers a solid foundation for building or upgrading your AR-15 platform.

I was looking for a dependable upper receiver to complete a lightweight AR build. I wanted something that offered a good balance between cost, durability, and accuracy. The DoubleStar DS-4 seemed to fit the bill perfectly.

Out of the box, the upper receiver has a no-nonsense, functional aesthetic. The anodized finish is evenly applied and looks durable. The weight feels appropriate for a 16″ barrel, not too heavy but not flimsy either.

I considered the Aero Precision M4E1 upper receiver, known for its enhanced features, and a Bravo Company Manufacturing (BCM) upper, praised for its exceptional quality. However, the DoubleStar DS-4 offered a more budget-friendly option without sacrificing essential features, allowing me to allocate more funds to other components. I also considered a complete upper from Palmetto State Armory, but went with DoubleStar due to wanting a more established brand.

I was cautiously optimistic upon receiving the DoubleStar DS-4. I had heard mixed reviews about DoubleStar in the past, but I hoped this particular upper would live up to its promises of reliability and accuracy. I was excited to finally get my project AR-15 built.

Real-World Testing: Putting DoubleStar DS-4 AR-15/M4 Flattop 16″ Upper Receiver to the Test

First Use Experience

I tested the DoubleStar DS-4 upper at my local outdoor shooting range. I fired approximately 200 rounds of various 5.56 NATO ammunition, including M193 and M855. The weather was clear and sunny, with a slight breeze.

The upper receiver performed admirably during the first range session. There were no malfunctions or failures to feed. I achieved decent accuracy at 100 yards with iron sights, which I was happy with.

The DoubleStar DS-4 was relatively straightforward to install onto my existing lower receiver. I did not need to make any modifications. I was able to adjust to the ergonomics of the upper without any difficulty.

Extended Use & Reliability

After several months and approximately 1000 rounds fired, the DoubleStar DS-4 continues to perform reliably. I have experienced no significant issues. The finish has held up well to regular use and cleaning.

There are only minor signs of wear on the brass deflector. The anodized finish remains intact. Cleaning the barrel and upper receiver is a simple process, requiring only standard AR-15 cleaning tools and solvents.

Compared to my previous experience with a cheaper, no-name upper receiver, the DoubleStar DS-4 is a significant improvement. It offers greater reliability and accuracy, making it a worthwhile investment. I also shot a friend’s Bravo Company upper and felt the DoubleStar was comparable in feel and accuracy.
