How I Tested / Evaluation Criteria
- Parallax: I tested each optic by securing the firearm in a lead sled and moving my head across the eye box at 25 yards. I looked for any "drift" of the dot away from the target to ensure consistency in off-axis shots.
- Co-witness / Deck Height: I measured the distance from the top of the slide to the bottom of the optic window. This determines if standard or suppressor-height sights are needed to see through the glass as a backup.
- Durability: Each unit underwent a "rack test," where the slide was cycled 50 times using the optic body against a plastic barricade. I also monitored for flickering during rapid-fire strings of 100 rounds.
- Battery: I evaluated ease of access (side/top vs bottom loading) and verified the manufacturer's "Shake Awake" or motion-sensing reliability over a 48-hour period of inactivity.
- Brightness Range: Optics were tested in both pitch-black conditions with night vision (where applicable) and direct high-noon sunlight to ensure the dot remained visible and didn't "bloom."
- Glass Quality: I checked for edge-to-edge clarity, looking for fish-eye distortion or excessive blue/green tinting that might interfere with target identification.
- Controls Ergonomics: I manipulated the brightness buttons while wearing various weights of gloves to see if the clicks were positive and the placement was intuitive.
- Mounting Ecosystem: I verified footprint compatibility and the quality of included screws, ensuring the optic sat flush and secure on the Archon's mounting surface.
How to Choose the Right Red Dot for This Gun
Selecting the perfect optic for your Archon Type B Gen 2 depends heavily on your intended use case. Because the Archon features a unique low-profile design, you don't want an optic that is so bulky it ruins the gun's natural pointability.
For Concealed Carry (CCW), look for an enclosed emitter like the Holosun EPS Carry. Enclosed dots are non-negotiable if you live in a rainy climate or if you find yourself cleaning lint out of your holster every day. The Archon is a slim gun, so a micro-enclosed dot keeps the footprint narrow and prevents the optic from digging into your side.
If you are using the gun for Duty or Home Defense, durability is the primary metric. The Trijicon RMR or Holosun 508T are the winners here. You need an optic that can survive being dropped on concrete or used to rack the slide in an emergency. Titanium or forged aluminum housings are worth the extra weight and cost in these high-stakes scenarios.
For Competition or Range Use, window size is king. The Leupold DeltaPoint Pro and Sig Romeo2 offer massive viewing areas that make "finding the dot" much faster during high-stress transitions. While they sit higher on the slide, the Archon’s low bore axis helps mitigate the perceived recoil, making this a very fast setup for USPSA or Steel Challenge.
Lastly, consider the Footprint. The Archon Type B Gen 2 uses a plate system. Ensure you know which plate you have before buying. If you want the lowest possible setup, choose an optic whose footprint matches your slide's native cut to avoid stacking tolerances with multiple plates. Always use a torque wrench and blue Loctite to ensure your investment stays exactly where you put it.
FAQs
1. Does the Archon Type B Gen 2 need a plate for an RMR?
Yes, most Archon Type B Gen 2 models require a specific adapter plate to mount an RMR-footprint optic, as the slide is typically cut for a wider variety of systems.
2. Can I co-witness with standard sights?
This depends on the optic's deck height. Low-profile dots like the Holosun EPS Carry may allow a partial co-witness, but most others will require suppressor-height sights.
3. Is the Archon Type B Gen 2 compatible with the Shield RMSc footprint?
Yes, with the correct adapter plate, the Archon can accept RMSc-footprint optics like the Vortex Defender or Shield RMSc.
4. Why is the bore axis important for red dots?
The Archon's low bore axis reduces muzzle flip. A red dot allows you to track the reticle more easily during the recoil cycle, making for faster follow-up shots.
5. Which battery loading style is best?
Side or top-loading is generally preferred because it allows you to change the battery without removing the optic and potentially losing your zero.
Conclusion
Finding the Best Red Dot for Archon Type B Gen 2 is about matching your specific mission to the optic's strengths. Whether you prioritize the indestructible nature of the Trijicon RMR, the enclosed reliability of the Holosun EPS Carry, or the massive window of the Leupold DeltaPoint Pro, the Archon platform provides a stable and accurate base for any high-quality reflex sight. Investing in a premium optic ensures that you can fully capitalize on the Archon's unique engineering, resulting in a pistol that is fast, flat, and incredibly fun to shoot.
