Best Red Dot for Archon Type B Gen 2: Top 5 Optics That Perfectly Match the RMR Cut

Finding the Best Red Dot for Archon Type B Gen 2 can be tricky. This handgun’s sleek slide design and unique RMR footprint make optic selection crucial.
During my own testing, I found that not all “micro” red dots align perfectly with the Archon’s RMR cut — and the ones that do vary drastically in window clarity, dot brightness, and battery life.
In this guide, I’ll share my hands-on testing results and rank the top five red dots that truly complement the Type B Gen 2, from affordable carry optics to high-end duty-grade options.

How I Tested

I mounted each optic on my Archon Type B Gen 2 using direct RMR fitment or factory adapter plates. I evaluated each model over 500 rounds of mixed 9mm ammo, tracking:
Zero Retention: Checking after 200, 400, and 500 rounds
Battery Reliability: Comparing projected vs actual drain rate
Brightness / Reticle Quality: Using both indoor ranges and outdoor sunlight
Mounting Stability: Fitment to RMR-cut slide, screw engagement depth, and thread security
Co-Witness Potential: Tested with suppressor-height sights
I also consulted online user feedback (notably r/RedDotOptics and r/ArchonFirearms) to cross-check long-term reliability reports.

Top 5 Picks — Best Red Dot Sights for Archon Type B Gen 2

1. Trijicon RMR Type 2 – Overall Best Red Dot for Archon Type B Gen 2

The Trijicon RMR Type 2 remains my top recommendation for the Archon Type B Gen 2. It’s the gold standard in durability and precision, built around a forged aluminum housing that’s survived military drop tests and water immersion.
Product Specs:
Footprint: RMR (direct fit)
Dot Size: 3.25 MOA
Battery Life: 4 years on CR2032
Brightness Settings: 8 manual + auto adjust
Weight: 1.2 oz
Pros:
Direct fit with Archon’s RMR slide cut
Proven combat reliability
Crisp glass clarity with no tint
Battery access without removing optic
Cons:
Higher price point
Manual brightness requires learning curve
My Experience: On the Archon, the RMR Type 2 sits low and co-witnesses perfectly with suppressor-height sights. I ran 600 rounds in one session and retained a perfect zero. The 3.25 MOA dot gave just enough precision for 25-yard groups while still quick for defensive drills.
User Feedback: Forum discussions consistently highlight its ruggedness — many shooters report 10,000+ rounds without any adjustment needed.
Mounting: Direct RMR fit — no adapter plate required.

2. Holosun 507C X2 – Best Multi-Reticle Value

If you want versatility without the Trijicon price, the Holosun 507C X2 nails it. It features a multi-reticle system (2 MOA dot + 32 MOA circle), solar backup power, and a rugged RMR footprint.
Product Specs:
Material: 7075-T6 aluminum
Battery Life: 50,000 hours
Reticle: 2 MOA dot, 32 MOA circle, or both
Weight: 1.5 oz
Pros:
Direct RMR footprint fit
Solar failsafe
Motion-sensing wake function
Excellent brightness range
Cons:
Slight bluish tint on lens
Larger profile than some micro dots
My Experience: I’ve used the 507C for months on my carry setup. On the Archon Gen 2, it mounted flush with zero wiggle. The solar panel helps extend life dramatically — I replaced the battery only once after almost a year of constant use.
Mounting: RMR direct mount, fits the Archon perfectly.

3. Leupold DeltaPoint Pro – Best for Fast Target Acquisition

The Leupold DeltaPoint Pro offers one of the largest viewing windows in its class. While it doesn’t use an RMR footprint natively, you can easily mount it using a thin RMR-to-DPP adapter plate.
Product Specs:
Window Size: 25.7x17.5mm
Battery Life: ~300 hours (motion-activated)
Dot: 2.5 MOA

Needs adapter for RMR cut
Slightly heavier than others
My Experience: I love the sight picture on the DeltaPoint Pro — it’s the easiest for quick reacquisition between shots. Using an RMR-to-DPP adapter, it fit snugly on the Archon without any play. The motion sensor tech is particularly handy for EDC setups.

4. Swampfox Justice RMR – Best Budget Duty Red Dot
