DoubleStar Complete Flattop Upper Receiver Review

Let’s Dive into DoubleStar Complete Flattop Upper Receiver

The DoubleStar Complete Flattop Upper Receiver offers an affordable entry point into the world of AR-15 builds and upgrades. DoubleStar promises a complete, ready-to-install upper receiver, forged from 7075-T6 aluminum with M4 feed ramps. This complete upper boasts T-markings, a forward assist, and a dust cover, and all for a price that’s hard to ignore.

I was looking to complete a budget AR build for recreational range use. Finding a reliable, yet inexpensive upper receiver was paramount. I needed an upper that would provide consistent performance without breaking the bank.

Upon unboxing, the DoubleStar Complete Flattop Upper Receiver felt surprisingly solid for its price point. The anodized finish appeared even and well-applied, and the included components seemed properly assembled. The overall build felt robust, suggesting it could withstand moderate use.

I also considered upper receivers from Aero Precision and Palmetto State Armory. However, the DoubleStar came in at a significantly lower price, making it the more attractive option for my budget build. Ultimately, the price point, along with the promise of a complete assembly, convinced me to choose the DoubleStar.

Initially, I was cautiously optimistic. Could a complete upper receiver at this price truly deliver reliable performance? Only time and rounds downrange would tell, but my first impression was that it had potential.

Real-World Testing: Putting DoubleStar Complete Flattop Upper Receiver to the Test

First Use Experience

I took the DoubleStar Complete Flattop Upper Receiver to my local outdoor range. It was mounted on a lower receiver I had assembled myself. The weather was dry with a slight breeze, ideal conditions for testing.

The upper receiver performed admirably, cycling rounds smoothly with minimal hiccups. I used a variety of ammunition, including both brass and steel-cased rounds, to gauge its reliability. The M4 feed ramps seemed to do their job, guiding rounds into the chamber without issue.

The upper receiver mounted easily on my lower. No specialized tools were needed, just standard AR-15 tools. I was initially concerned that there would be excessive play between the upper and lower, but the fit was surprisingly tight.

Extended Use & Reliability

After several months of consistent range use, the DoubleStar Complete Flattop Upper Receiver has held up well. I’ve put several hundred rounds through it without any major malfunctions. The anodized finish shows some minor wear marks, but that is expected with repeated use.

I’ve been diligent about cleaning and lubricating the upper after each range session. This includes cleaning the bore and applying a light coat of oil to the bolt carrier group. The upper is fairly simple to disassemble and clean, requiring only basic tools and solvents.

Compared to other budget-friendly uppers I’ve used, the DoubleStar has exceeded my expectations in terms of reliability. It has proven to be a solid performer for recreational shooting. I’ve had fewer issues with it than I had with some of the more expensive uppers I’ve used in the past.
