C-MORE CRC Tactical Railway Red Dot Sight 4 Moa Dot Black. Just like our competition sights the CRC head up display provides an unobstructed sight picture in which the red dot hovers on the sight line illuminating the point of impact on the target creating the fastest target acquisition in existence and unlimited eye relief. Similarly it uses a beam-splitter lens made of glass; hard coated for maximum scratch resistance and light transmission while the parallax free design enables targets to be acquired without the need to center the dot in the lens. Designed for slide mounting on pistols and optimized for standard and sub compact models the CRC features a super low profile for easier co-witnessing with the pistols iron sights and a common compact footprint (same as RMSc) and mounting pattern (same as Shield Delta Point Pro and JPoint). The sight is available in a 4 or 6 MOA dot size with 10 brightness levels for extreme low light through super bright day light conditions. The intensity is precisely controlled using manual Up and Down push button switches and returns to the previous intensity when turned on. Hardened Electronics provide increased reliability and a MSS Motion Sensing System (Shake to Wake) that will power down the dot to standby mode to save battery life when no motion or vibration is detected for 3 minutes. The dot will power on immediately when motion or vibration has been detected. The CRC has a black anodized aircraft alloy housing for maximum durability 1 moa precision click adjustments for windage and elevation IPX7 waterproof to 1m and uses a bottom load CR2032 lithium battery that can provide 50000 hours of runtime (usage and intensity dependent) and a low battery indicator.
