Let’s Talk About DoubleStar .22 Nosler Upper w/Diamond National Free Float Handguard
The DoubleStar .22 Nosler Upper w/Diamond National Free Float Handguard is a complete upper receiver assembly designed for AR-15 platforms, chambered in the high-velocity .22 Nosler cartridge. This upper boasts a 24″ stainless steel bull barrel and a free-float handguard, promising both accuracy and long-range capabilities. DoubleStar aims to deliver a competition-ready upper right out of the box.
I’ve always been fascinated by flat-shooting cartridges capable of defying wind drift at extended ranges. My search for a high-performance AR upper that could reliably reach 1000 yards led me directly to the .22 Nosler, and consequently, to this offering from DoubleStar. The promise of a complete, drop-in solution with a match-grade barrel and free-float handguard was incredibly appealing.
Upon unboxing, the DoubleStar upper presents a robust and well-machined appearance. The weight is substantial, owing to the bull barrel, but it feels balanced. The anodized finish is even and durable, while the handguard is solid and comfortable to grip.
Compared to similar uppers from companies like Alexander Arms (in .17 HMR) or Wilson Combat (in .223 Wylde), the DoubleStar offered a compelling combination of price and advertised performance in the .22 Nosler chambering. While other options exist, the DoubleStar promised a complete, ready-to-go package. My initial impression was one of cautious optimism, tinged with excitement at the potential for reaching out and touching targets at extreme distances.
Real-World Testing: Putting DoubleStar .22 Nosler Upper w/Diamond National Free Float Handguard to the Test
First Use Experience
My initial testing of the DoubleStar .22 Nosler Upper w/Diamond National Free Float Handguard took place at a local shooting range with distances out to 600 yards. The day was clear and mild, with a light breeze, perfect conditions for dialing in the optic and getting a feel for the upper. Immediately, the flat trajectory of the .22 Nosler was apparent, significantly reducing the holdover needed compared to my .223 Wylde AR.
The upper performed reliably, with no malfunctions in the first 50 rounds. It was easy to get used to the rifle-length gas system and the trigger pull. There was, however, a noticeable amount of gas blowback, especially when using a suppressor.
Extended Use & Reliability
After several months of consistent use, including range trips and varmint hunting expeditions, the DoubleStar upper has proven to be relatively reliable. The anodized finish has held up well, showing minimal signs of wear, even after being exposed to brush and inclement weather. Cleaning is straightforward, with easy access to the bore and gas system.
Compared to previous experiences with other AR uppers, the DoubleStar performs as expected in terms of accuracy. However, the increased gas blowback requires more frequent cleaning, especially of the bolt carrier group. The promise of “supersonic projectiles out to 1000 yards” is achievable, though requires precise ammunition selection, careful ballistic calculations, and favorable wind conditions.

Performance & Functionality
The DoubleStar .22 Nosler Upper w/Diamond National Free Float Handguard performs its primary function of delivering accurate and reliable long-range performance commendably. The accuracy is easily sub-MOA with match-grade ammunition. Reliability is generally good, although gas blowback can be an issue with certain suppressors.
The key strengths lie in the barrel’s accuracy and the flat-shooting nature of the .22 Nosler cartridge. A potential weakness is the need for specialized .22 Nosler magazines, which are less common and more expensive than standard AR magazines. The upper meets expectations for accuracy, but exceeds them for gas blowback.
Design & Ergonomics
The build quality of the DoubleStar upper is robust. The materials used feel durable. The overall weight, while significant, contributes to stability and recoil management. The handguard is comfortable to grip and provides ample space for mounting accessories.
The upper is relatively user-friendly, requiring no specialized tools for installation onto a compatible AR-15 lower receiver. However, familiarity with AR platform rifles is recommended.
Durability & Maintenance
The DoubleStar .22 Nosler Upper w/Diamond National Free Float Handguard appears to be built to last, with high-quality materials and a durable finish. Regular cleaning and lubrication are essential for maintaining optimal performance, particularly given the gas blowback.
Maintenance is relatively straightforward, with standard AR-15 disassembly procedures applicable. The barrel and gas system should be cleaned after each range session to prevent fouling.
Accessories and Customization Options
The DoubleStar upper comes with a National Match Free Float Handguard and a Picatinny rail aluminum gas block. Customization options are plentiful, including optics, muzzle devices, and charging handles.
The upper is compatible with any standard AR-15 lower receiver and most AR-15 accessories. However, remember that you’ll need magazines specifically designed for the .22 Nosler cartridge.
