Why choose this optic?

• Universal Compatibility: Works seamlessly with Umarex Optic Adapter Plates and fits C-More footprint standards.
• Versatile Mounting: Includes Picatinny rail mount for quick installation on a wide range of airguns and airsoft platforms.
• Clear Sight Picture: Anti-reflex, multi-coated glass ensures optimal visibility in various lighting conditions.
• Dual Brightness Modes: Choose from two intensity levels for the 8 MOA red dot using a simple side push button.
• Back-Up Sight Feature: Integrated auxiliary rear sight keeps you on target even when the red dot is off.
• Parallax-Free & 1x Magnification: Keeps your focus on the target without distortion or shift.

Why not?

• Bottom-Mounted Battery: Changing the CR1632 battery requires removing the sight from the rail.
• Only Two Brightness Levels: Limited adjustment range compared to advanced red dots with multiple brightness settings.
• Larger Dot Size: The 8 MOA dot may be too large for precise, long-distance targeting.

Pro Tip: Pair the RDS8 with Umarex’s MOS 1 optic adapter plates for a streamlined optic upgrade on your GLOCK-style airgun. Always zero your optic with your chosen BB weight for optimal performance. And remember—because of the bottom battery design, have a backup optic or iron sight plan in case you need to swap batteries mid-game.
