Let’s Talk About Seekins Precision NX16 Complete Upper Receiver
The Seekins Precision NX16 Complete Upper Receiver is not just another AR-15 upper; it’s a statement. It is a testament to precision engineering, lightweight design, and uncompromising quality from Seekins Precision. I was immediately drawn to its unique skeletonized aesthetics combined with the promise of exceptional performance. This upper receiver is designed for those who demand the best in their AR platform, whether for tactical applications, competition shooting, or building a premium SBR.
For years, I’d been searching for a .300 Blackout upper that could deliver both exceptional accuracy and minimal weight, without sacrificing reliability. Many of the lightweight options I considered felt flimsy or lacked the features I needed, like a quality bolt carrier group and a solid muzzle device. The NX16 seemed to strike that perfect balance.
Upon unboxing, the first thing that struck me was the fit and finish. The anodizing was flawless, and the machining was incredibly precise. It felt solid and well-built, despite its aggressively skeletonized design. The weight was noticeably less than my standard AR upper, which was a welcome surprise.
Compared to other uppers in this price range, like those from Bravo Company Manufacturing (BCM) or Daniel Defense, the NX16 stood out due to its unique aesthetics and the included components. While BCM and Daniel Defense offer excellent reliability, the Seekins Precision product came complete with a BCG, charging handle, and adjustable gas block, adding significant value. My initial excitement only grew as I prepared to take it to the range.
Real-World Testing: Putting Seekins Precision NX16 Complete Upper Receiver to the Test
First Use Experience
My first outing with the Seekins Precision NX16 Complete Upper Receiver was at my local shooting range, primarily focused on accuracy testing. I mounted it on a dedicated AR pistol lower with a quality brace, and ran a variety of .300 Blackout ammunition through it, from subsonic to supersonic. The upper performed flawlessly, cycling reliably with every round.
The adjustable gas block proved invaluable in fine-tuning the gas system for different ammunition types. I particularly appreciated how easily it was to adjust, even with gloved hands. I also tested it during a slightly drizzly day and the anodized finish proved to be quite resistant to water and didn’t affect the grip or the firearm’s functionality.
There were no malfunctions, failures to extract, or any other issues that plagued some of my previous builds. It was remarkably smooth right out of the box.
Extended Use & Reliability
After several months of regular use, the Seekins Precision NX16 Complete Upper Receiver continues to impress. It has consistently delivered reliable performance, regardless of the conditions. I have used it in temperatures ranging from below freezing to over 90 degrees Fahrenheit, with no noticeable impact on its performance.
The anodized finish has proven to be incredibly durable, showing minimal signs of wear even after being subjected to rough handling and exposure to the elements. Cleaning is simple; a standard AR cleaning kit and some solvent are all that’s needed to keep it running smoothly. Compared to some of the more budget-friendly uppers I’ve used, the NX16 far surpasses them in both reliability and durability.
