How to Choose the Right Red Dot Sight for This Gun
When shopping for the best red dot for the Stealth Arms Platypus, you should consider:
1. Footprint Compatibility
The Platypus typically accepts RMR footprints natively. Avoid sights that require obscure or proprietary mounts unless you’re fine with buying extra adapter plates.
2. Window Size
Larger windows are easier for fast shooting. For carry, compact sights like the 507K or RMRcc are great, but for versatility, go for full-size windows.
3. Durability
Your red dot should be able to survive drops, rain, and recoil. Forged or billet aluminum housings are ideal.
4. Battery Access
Top-loading battery compartments save time. Optics that require removal for battery changes are a hassle.
5. Reticle Type
Multi-reticle systems offer flexibility. You can choose a single dot, circle-dot, or even larger reticles depending on your eyes and use-case.
FAQs
1. Can I install an RMR footprint red dot directly on the Stealth Arms Platypus?
Yes, the Platypus is RMR-cut, so sights like the RMR Type 2 and Holosun 507C fit without adapters.
2. Do I need backup iron sights with a red dot?
I recommend co-witness sights if you’re using the Platypus for defense. Many optics are low enough to co-witness with suppressor height irons.
3. Is auto-brightness better than manual control?
Auto-brightness is convenient but can be unpredictable. Manual brightness offers more control for competitive shooting.
4. What MOA dot size should I choose?
A 3 MOA dot is a sweet spot—precise enough for distance, big enough for quick shots. Larger MOA dots like 6 are better for close range.
5. How long do red dot batteries typically last?
Anywhere from 1 to 5 years depending on the model and brightness settings. Holosun’s solar backup extends that range.
6. Can I conceal carry with these optics?
Yes, especially if paired with a slim optic like the Holosun 507K or Trijicon RMRcc.
7. Do red dots hold zero after heavy recoil?
Quality red dots like Trijicon or Holosun do. Budget optics can sometimes shift zero after repeated shooting.
Conclusion
The best red dot for Stealth Arms Platypus boils down to your intended use. If you want a battle-proven workhorse, the Trijicon RMR Type 2 is unbeatable. For budget-conscious shooters, the Holosun 507C offers incredible performance. Regardless of your choice, each option listed above pairs beautifully with the Platypus in both form and function.
