CIA CAOP0102 OBSIDIAN LITE ENCLOSED RFL SGT

The Century Arms Obsidian Lite is an enclosed red dot sight built for shooters who want a compact, protected optic without the bulk of a full-tube design. If you're running a modern rifle, pistol, or shotgun and need a sight that stays clean and ready in the field, this enclosed reflex sight delivers the speed and simplicity red dots are known for while keeping the lens protected from dust, brush, and the elements.

Enclosed red dot sights have a following among hunters and tactical shooters for good reason: the housing shields your glass and reticle from weather and snags that might compromise an open design. The Obsidian Lite carries that philosophy in a lighter package, making it a practical choice if you're building a rifle that doesn't need to be stripped down to the gram but does need to stay reliable across seasons and conditions.

Century Arms engineered this sight for modern sporting rifles and patrol-grade carbines. The reflex design means fast target acquisition and both-eyes-open shooting—two things that matter whether you're hunting, running a course, or training at the range. The enclosed housing and compact footprint make it a natural fit for folks who value protection and portability equally.

Key Features

• Enclosed reflex design protects the lens from dust, dirt, and weather
• Compact and lightweight for rifles and tactical carbines
• Fast target acquisition and both-eyes-open shooting capability

Frequently Asked Questions

What kind of rifles and firearms work with the Obsidian Lite?

The Obsidian Lite is designed as a reflex sight for rifles, carbines, and other long guns. If you have questions about fit on a specific platform, our team can help—stop by or call.

What's the difference between an enclosed and open red dot sight?

Enclosed sights have a housing that shields the lens and reticle from the elements and accidental contact. They're more weather-resistant and tend to stay cleaner in the field. Open designs are typically lower-profile and sometimes lighter, but offer less protection. The Obsidian Lite trades a bit of profile for real durability.

Do I need special mounting hardware?

The Obsidian Lite mounts via reflex sight standard interfaces. Confirm compatibility with your rifle's rail or mounting system before purchase, or let us know what you're running and we can point you in the right direction.
