The CT RAD Pro (Rapid Aiming Dot) Electronic Sight is a full-size Open Reflex Sight for full frame pistols. Featuring a red 3 MOA aiming dot, the CT RAD Pro has a recessed and fully multi-coated lens with a large quick acquisition window. The CT RAD Pro comes with the CT RADIANT Ambient Light Sensor that automatically adjusts the aiming dot's brightness to the surrounding lighting condition. The CT MOTION Sensor detects movement of the firearm and automatically turns the reflex sight on. The sight powers off after 2 minutes of zero movement. The CT RAD Pro comes with an AUTO Shutoff Function that automatically shuts off after 8 consecutive hours of operation to conserve battery life and a manual ON/OFF Function that allows you to turn on or off the sight by using the side brightness buttons.The CT RAD Pro is easily installed on an optics cut slide using the CT RAD footprint that is also compatible with the Docter footprint. It also comes with an additional Low Profile Pic Rail to mount your Pro to most any MILSPEC Pic rail. Textured sides allow for a secure grip when racking the slide. The CT RAD(TM) Pro has large brightness setting buttons for easy use even with gloves on. Made of 7075 Series Aerospace Aluminum, it is 30% stronger than most industry standard sights made with 6061 Series Aluminum. The entire CT RAD family has an Innovative top strap design that deflects force if the sight is dropped. Our engineers developed a better way to reduce stress on the lens of reflex sights. By combining out-of-the-box thinking with next-level physics, we designed a system that both re-enforces your optic and reduces stress if it happens to get dropped. All this comes with our CRIMSON Protect Lifetime Warranty.Features:RED DOT PLATFORM: FULL-SIZED HANDGUNSRED DOT MOUNT: ADDITIONAL M1913 PICATINNY LOW MOUNT INCLUDEDFOOTPRINT: CT RAD FOOTPRINT(Doctor Optic)RETICLE: 3 MOA RED DOTUSER ADJUSTABLE: WINDAGE AND ELEVATIONBATTERY TYPE: CR2016BATTERY LIFE: 20,000 HOURS (2+ YEARS)BATTERY ACCESS: TOP MOUNTCONSTRUCTION: 7075 SERIES ALUMINUMDURABILITY: IPX7 WATERPROOF, SHOCK, IMPACT, AND FOG RESISTANTSHAKE-TO-WAKE: CT MOTIONAMBIENT LIGHT SENSOR: CT RADIANT
