First Impressions of ODIN Works AR-15 22 ARC 21in Threaded Barrel
The ODIN Works AR-15 22 ARC 21in Threaded Barrel promises to bring the heat of the .22-250 to the AR-15 platform, a concept that immediately piqued my interest. As someone who’s spent over a decade tinkering with and testing AR builds for various applications, the thought of a cartridge that combines flat-shooting performance with the AR’s modularity is extremely compelling. ODIN Works has a reputation for quality components, so my expectations are high going into this review.
For years, I’ve been chasing the perfect varmint AR, something with long-range capability and minimal recoil for quick follow-up shots. Other AR cartridges like the .223 Wylde and 6.5 Grendel fell short in different areas, either lacking the raw velocity or pushing the limits of the AR-15’s physical size. This barrel presented a potential solution.
Upon unboxing, the first thing that struck me was the overall fit and finish. The stainless steel had a clean, even appearance, and the included tunable gas block felt solid and well-machined. The barrel’s weight felt appropriate for its length, suggesting a good balance between portability and accuracy.
Comparing this to barrels from companies like Ballistic Advantage or Criterion, the ODIN Works barrel immediately felt like a step up in terms of attention to detail. I chose this barrel hoping to harness its 21″ length, 1-7 twist rate, and included gas system to achieve optimal performance with heavier .22 ARC projectiles. My initial impression is one of cautious optimism; I’m eager to see if it lives up to the hype on the range.
Real-World Testing: Putting ODIN Works AR-15 22 ARC 21in Threaded Barrel to the Test
First Use Experience
I tested the ODIN Works AR-15 22 ARC 21in Threaded Barrel at my local range, focusing on evaluating its accuracy and reliability with various .22 ARC loads. The conditions were sunny with a light breeze, providing a relatively controlled environment. The barrel was installed on a dedicated AR-15 upper receiver, paired with a quality lower and a crisp Geissele trigger.
The initial range session revealed impressive accuracy potential, with several five-shot groups hovering around the 0.75 MOA mark using factory Hornady 62gr ELD-VT ammunition. The rifle cycled smoothly, and the tunable gas block allowed for fine-tuning to minimize felt recoil and ensure reliable operation. There were no initial malfunctions or issues of concern.

The stainless steel construction has held up well, showing no signs of rust or corrosion despite exposure to varying weather conditions. Cleaning is relatively straightforward, and the bore maintains its smooth finish.
The barrel continues to deliver consistent accuracy, with minimal degradation in performance over time. I’ve experimented with handloading, and the barrel has shown a willingness to shoot even tighter groups with optimized loads. Compared to previous AR builds, the ODIN Works barrel represents a significant step up in both accuracy and overall quality.
