• 💰 Affordability (under $100 retail)

• 🔋 Battery Life & Auto-Off features

• 🧲 Mount Compatibility (Picatinny/RIS)

🎯 Pro Tips for Choosing & Mounting:

✅ Zero Your Sight at 15–25 meters for most engagements

✅ Co-Witness with Iron Sights if possible for backup
✅ Adjust Brightness based on field lighting—too bright = poor contrast
