CIA CAOP0001 ONYX C REDDOT RSMSC FOOTPRINT

The Century Arms ONYX C is a red dot sight built on the Aimpoint Micro footprint, giving shooters a compact, fast-acquisition optic for rifles, shotguns, and carbines where speed matters more than magnification. If you run an AR, a tactical shotgun, or any modern sporting rifle and want a sight that cuts through clutter to put the dot on target in a fraction of a second, this is the kind of workhorse accessory that pays for itself on the first range trip.

Red dot sights live or die by durability and reliability—and the ONYX C is built to handle real use. The Micro footprint is an industry standard, so if you ever need to swap optics or upgrade your setup, compatibility isn't going to be a headache. Whether you're zeroing a home-defense carbine, running drills at a 3-gun match, or just putting rounds downrange, a quality red dot that holds zero is non-negotiable.

Century Arms brings practical, no-nonsense engineering to their optics line. The ONYX C delivers the simplicity you need: point, aim, shoot. No complicated turrets to fiddle with, no parallax adjustments to second-guess yourself on. Just a clean sight picture and muscle memory.

Frequently Asked Questions

Will the ONYX C fit my AR-15 or rifle?

The ONYX C uses the Aimpoint Micro footprint, which is compatible with any optic mount designed for that standard. Check that your rail or upper receiver supports Micro-pattern mounts, and you're good to go.

What's the difference between a red dot and a magnified scope?

A red dot sight gives you unlimited eye relief and a wide field of view, making target acquisition fast—perfect for close to mid-range shooting, home defense, and hunting in brush. Magnified scopes excel at distance precision but slow down point-and-shoot speed. Many shooters run a red dot for versatility.

Is the Aimpoint Micro footprint easy to find mounts for?

Yes. The Micro footprint is one of the most widely supported patterns in the industry. You'll find mounting solutions from dozens of manufacturers—risers, side mounts, quick-detach bases, and more.
