The Swampfox Optics Sentinal II 1X20MM Red 3 MOA Dot Tritium Rear Micro Sight Made a Bold First Impression
The Swampfox Optics Sentinal II 1X20MM Red 3 MOA Dot Tritium Rear Micro Sight steps into the micro red dot arena aiming to provide a durable and versatile aiming solution, with the added benefit of tritium illumination for low-light scenarios. This optic from Swampfox intends to be a reliable companion for concealed carry pistols and other compact firearms where a minimal footprint is crucial.
My journey to the Sentinal II began when I was seeking a red dot sight for my EDC pistol that wouldn’t significantly increase its bulk. Many of the reflex sights I’d used in the past were either too large for comfortable concealed carry or lacked the durability I expect from my everyday tools. I yearned for a truly compact optic that was also rugged and offered usable illumination in all lighting conditions, including complete darkness, without relying solely on battery power.
Unboxing the Sentinal II, I was immediately struck by its diminutive size. The sight felt incredibly solid in hand, hinting at a robust build quality despite its light weight. The black finish appeared even and durable, and the overall design exuded a sense of purpose and efficiency.
I considered several other micro red dots, including the Trijicon RMRcc and the Holosun 507k. I ultimately chose the Swampfox Sentinal II primarily for its combination of a smaller footprint than the RMRcc, the tritium backup illumination, and potentially better value. My first impression was a pleasant surprise: it felt like a serious contender in the micro red dot market.
Real-World Testing: Putting Swampfox Optics Sentinal II 1X20MM Red 3 MOA Dot Tritium Rear Micro Sight to the Test
First Use Experience
My initial testing occurred at an indoor shooting range and an outdoor range, spanning various lighting conditions. I mounted the Sentinal II on a Glock 43X MOS, a popular concealed carry pistol. It was very easy to mount, and was zeroed within 10 shots at 15 yards.
The optic performed admirably in both environments. The 3 MOA dot was crisp and easy to acquire, and I noticed no parallax issues during rapid target transitions. Even when transitioning from bright sunlight into the dimmer indoor range, the dot’s brightness was easily adjustable, although the tritium was there to provide some light. There were no issues with rain.
The first-time use was encouraging. The sight provided a clear and consistent aiming point, significantly improving my target acquisition speed compared to iron sights. The dot remained stable throughout multiple magazines, and the controls were intuitive and easy to use.
Extended Use & Reliability
After several months of consistent use, including weekly range sessions and daily carry, the Sentinal II has held up remarkably well. It has remained firmly mounted.
I’ve observed no noticeable wear and tear on the housing. The glass remains clear, and the adjustments still feel precise. The tritium illumination continues to glow consistently in low-light conditions, providing a constant backup aiming point should the battery fail.
Maintaining the Sentinal II is straightforward. A quick wipe with a microfiber cloth is usually sufficient to remove any smudges or debris from the lens. So far, it has outperformed my expectations for a micro red dot in its price range.

Performance & Functionality
