The Ruger ReadyDot is a 1X reflex sight built around the Shield RMSc footprint — native fit for the Ruger MAX-9 plus any compact handgun with an RMSc-cut slide. A fixed, factory-zeroed 15 MOA red dot drives fast target acquisition at pistol distances, and the fiber-optic light source means no battery, no buttons, and nothing to fail mid-string. The polymer housing is shock- and water-resistant with a multi-layer-coated lens that stays clear through holster wear and weather.

Features:

• Reticle: Fixed 15 MOA red dot, factory zero
• Light source: Fiber-optic (battery-free, auto-brightness)
• Magnification: 1X
• Lens: 12mm impact-resistant polymer, multi-layer coated
• Footprint: Shield RMSc (Ruger MAX-9 native; fits any RMSc-cut slide)
• Sealed, water-resistant housing
• Includes mounting hardware

Compatibility note: confirm your slide cut matches Shield RMSc before install — adapter plates are required for non-RMSc footprints.
