Ruger ReadyDot Optic 90742 - 1x 15 MOA Red Dot Reticle, Black

The Ruger ReadyDot Optic is a fiber-illuminated red dot sight engineered for fast, battery-free shooting on compatible compact handguns. Designed with the Ruger MAX-9 in mind, this reflex sight uses its fiber gathering system to provide a bright reticle in daylight conditions without relying on batteries—a real advantage for everyday carry when you don't want to fuss with power management. The 1x magnification and fixed 15 MOA red dot keep your focus on the target, and the simple, clean sight picture works well at the ranges where most EDC pistol shooting happens.

The ReadyDot mounts on standard RMSc footprints, which means it's compatible with a range of optics-ready compact pistols beyond just Ruger platforms. The fixed elevation and windage design keeps things reliable and uncomplicated—there's nothing to dial, nothing to zero once it's mounted right. The sight profile was purposefully shaped to help your eyes find the dot quickly, whether you're drawing from concealment or working from ready. If you're running suppressor-height sights on your carry gun, the ReadyDot will co-witness to them, giving you a reliable backup aiming method if the optic ever fails.

Installation is straightforward: the package includes a T10 Torx wrench and two M4x0.7 8mm mounting screws. That said, fitment and screw specs can vary between different optics-ready pistols, so verify compatibility with your firearm's manufacturer before mounting. This is a genuine Ruger factory accessory built to Ruger's standards.

Frequently Asked Questions

Will the ReadyDot work on my compact pistol?

The ReadyDot uses a standard RMSc footprint, so it's compatible with many optics-ready compact handguns—not just the MAX-9. However, mounting hardware and adapter plates vary by manufacturer. Contact your firearm maker to confirm compatibility and correct screw specifications before installation.

Do I need a battery for the fiber-illuminated reticle?

No. The ReadyDot uses a fiber-gathering system to illuminate the reticle in daylight, so there's no battery to worry about. This makes it ideal for concealed carry where you want zero maintenance and zero battery failures.

Can I use this sight with iron sights?

Yes. If your pistol has suppressor-height sights, the ReadyDot will co-witness to them, giving you a backup aiming method. This is a useful safety feature in case the optic is ever damaged or blocked.

What's included in the box?

The sight comes with a T10 Torx wrench and two M4x0.7 8mm mounting screws for installation on compatible platforms. Make sure to verify the correct screw specifications for your specific firearm before mounting.
