Ruger

The Ruger ReadyDot is an ultra-reliable 1X reflex sight designed specifically to co-witness with the Ruger MAX-9 pistol but the low profile sight fits any compact handgun with a standard Shield RMSc footprint. It is a fixed non-adjustable sight with a large 15 MOA dot optimized for rapid target acquisition at pistol distances. The fixed co-witnessed dot avoids the necessity for delicate adjustment mechanisms making this one of the most rugged and reliable waterproof and shock resistant pistol optics available. - Light Source: Light-gathering fiber optic (battery not required) - Brightness Adjustment: Automatic based on ambient conditions - Aiming Dot: Red 15 MOA dot - Magnification: 1X (no magnification) - Lens: 12mm Impact resistant optical grade polymer with multi-layer coating - Dimensions: Sight only (Length x width x height) 1.6 x 0.9 x 0.9 inches - Weight: 0.3 ounces - Footprint: Fits pistols and mounting plates designed for Shield RMSc footprint - Parallax free distance: 10 yds - Waterproof - Also included: 2 x M4 x 0.7 8mm screws T10 torx wrench for mounting
