The CT RAD(TM) Micro (Rapid Aiming Dot) is an ultra-compact open-reflex sight purpose-built for compact and subcompact pistols. With a crisp 3 MOA red aiming dot and the CT RADIANT(TM) ambient light sensor, the Micro automatically adjusts reticle brightness for quick acquisition in changing light. Its recessed, fully multi-coated lens offers a large, unobstructed sight window while protecting the optic from impacts and glare. Machined from 7075-series aerospace aluminum for strength and durability, the Micro also features a reinforced top-strap design to deflect impact forces away from the lens, and a rear-sight notch to co-witness with factory front iron sights for rapid fallback.
