ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight Review

First Impressions of ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight

For years, I’ve trusted iron sights, but the aging eyes are not what they once were, making target acquisition a bit slower. The ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight promised a compact, RMR-footprint optic that could potentially solve this problem without breaking the bank. I was intrigued by the claim of always-on functionality with automatic brightness adjustment, features usually found in higher-priced optics.

My primary motivation was to improve my speed and accuracy with my EDC pistol. I was particularly looking for a red dot that wouldn’t add significant bulk to the slide and offered reliable performance in varying lighting conditions.

The ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight arrived well-packaged. My first impression was that it seemed surprisingly robust for its size and price. Compared to the Trijicon RMR and Holosun 507C, two popular options, the Stingray appeared smaller, which was a plus for concealed carry. Initially, I was excited to see how it would perform compared to more expensive optics, hoping for a budget-friendly solution that didn’t sacrifice too much in quality.


Real-World Testing: Putting ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight to the Test

First Use Experience

My initial testing took place at an indoor shooting range. I wanted to assess the ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight’s dot clarity and ease of target acquisition in a controlled environment. The sight picture was clear, and the 6 MOA dot was easily visible, even with the range’s bright lighting.

I ran into my first hiccup while zeroing. The adjustment clicks felt mushy and indistinct. After about 50 rounds, I managed to dial it in. The automatic brightness adjustment worked well, adapting to the changing light conditions as I moved between different shooting bays.

Extended Use & Reliability

After several months of regular use, the ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight has held up surprisingly well. There are some minor scratches on the anodized finish, but the lens remains clear. Cleaning is simple; a quick wipe with a microfiber cloth is usually sufficient.

Compared to a Holosun I own, the ADE Advanced Optics Stingray doesn’t quite match its ruggedness, but it has proven reliable enough for my needs. While the mushy adjustments are a consistent annoyance, the optic’s overall performance has been adequate, especially considering the price point.

Breaking Down the Features of ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight

Specifications

  • The ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight boasts a 6061 Aircraft Aluminum construction, finished with a durable anodized coating. This ensures a lightweight yet sturdy build capable of withstanding typical handgun recoil.
  • It offers 1x magnification through a 25.7 mm objective lens for a wide field of view. The red dot reticle is 6 MOA, designed for quick target acquisition, while the sight features unlimited eye relief.
  • ADE Advanced Optics has designed the Stingray to fit any pistol mounting plate/slide/cut compatible with Trijicon RMR/SRO, Holosun 407C/507C/508T. This compatibility greatly expands its usability.
  • It utilizes a CR2032 3V battery, which ADE Advanced Optics claims will provide approximately one year of battery life. The optic weighs a mere 0.88 oz and has overall dimensions of 1.6 in (Length) x 1.1 in (Width) x 0.93 in (Height).

Performance & Functionality

The ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight functions adequately for its intended purpose. The automatic brightness adjustment is a convenient feature, allowing the dot to remain visible in various lighting conditions.

While the clarity of the glass is good, the mushy windage and elevation adjustments are a significant drawback, making precise zeroing difficult. Despite this, once zeroed, the optic holds zero well, providing acceptable accuracy at typical handgun ranges.

Design & Ergonomics

The ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight is designed with a compact footprint, making it suitable for concealed carry. The aluminum construction provides a sturdy feel without adding excessive weight to the pistol.

The integrated “back up iron sight” curve with two white dots is a unique design element, but its effectiveness is limited due to the sight’s short overall height. There is a learning curve associated with any red dot sight, but the Stingray’s simple design makes it relatively easy to adapt to.

Durability & Maintenance

The aluminum housing of the ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight seems reasonably durable, though not on par with higher-end optics like Trijicon. With proper care, the optic should last for several years of regular use.

Maintenance is straightforward; the lens can be cleaned with a lens cloth, and the battery is easily replaceable. I would recommend regularly checking the mounting screws to ensure they remain properly torqued.

Accessories and Customization Options

The ADE Advanced Optics RD3-019 Stingray Micro Red Dot Sight comes with screws for several Optics Ready handguns. It does not include a mounting plate.

Due to its RMR footprint, the optic is compatible with a wide variety of aftermarket mounting plates and adapters. I would also recommend purchasing a quality lens cleaning kit to maintain optimal clarity.
