The CT RAD(TM) Micro (Rapid Aiming Dot) is an ultra-compact open-reflex sight purpose-built for compact and subcompact pistols. Featuring a bright 5 MOA green aiming dot and an automatic CT RADIANT(TM) ambient light sensor, the Micro adapts its reticle brightness to surrounding conditions for instant, reliable acquisition. Its recessed, fully multi-coated lens provides a large sight window with impact protection, and the rear-sight notch allows quick alignment with your front iron sight. Machined from 7075-series aerospace aluminum and engineered with a reinforced top-strap to deflect impact forces away from the lens, the Micro pairs durability with a micro footprint compatible with CT micro(TM), Shield RMSA(R), and JPointA(R) optic cuts. Backed by CRIMSON Protect Lifetime Warranty, it's a compact sight that's built to last.
