Colt Optics CSQ-1 Reflex Red Dot Sight 0.43 MRAD/1.5MOA Black. It runs one of the largest collimating lenses on the market for a massive unobstructed sight picture and the squared window gives your brain natural reference points to center the aiming point with less processing time. Faster decision faster action. Built from 7075-T6 aircraft-grade aluminum fully enclosed MIL-STD shock-rated and submersible the CSQ-1 is made to be trusted. A large top-mounted control sits ready for ambidextrous gloved-hand use with a dedicated night-vision button to jump between daylight and NV-compatible settings in an instant. The custom multi-role reticle delivers MRAD ranging and BDC holds or switches to a clean single dot when you want simplicity. Shake-awake wakes it the moment you move auto shut-off saves power when you dont and a single CR2032 keeps the dot lit for up to 50000 hours.
