The Crimson Trace CT RAD Pro is a full-size Open Reflex Sight designed for full frame pistols and adaptable to long guns, delivering a green 5 MOA aiming dot through a recessed, multi-coated lens with a generous quick acquisition window. Equipped with the CT RADIANT Ambient Light Sensor, the dot brightness automatically adjusts to surrounding conditions, while the CT MOTION Sensor detects firearm movement and powers the sight on, with an auto shutoff after two minutes of inactivity to conserve battery life and an eight-hour auto shutoff to ensure reliability when idle. A manual ON/OFF function via side brightness controls provides immediate control when needed. Installation is streamlined on optics cut slides using the CT RAD footprint, compatible with the Docter footprint, and includes a Low Profile Pic Rail for mounting on MILSPEC rails, plus textured sides for secure racking and large brightness buttons that remain easy to operate with gloves. Crafted from 7075 aerospace aluminum, the CT RAD Pro is engineered with an innovative top strap design to deflect impact and reduce lens stress, reinforcing durability in rapid or challenging field conditions. All Crimson Trace components are backed by the CRIMSON Protect Lifetime Warranty, ensuring long-term performance and confidence in critical shooting applications.
