The new Brownells CQB T-Dot Holographic Sight pairs EoTech's EXPS2 battlesight with a custom-designed reticle to deliver fast aiming on targets closer than 10 yards and precise aiming for longer range targets. The bottom of the 65-minute red circle is cut out and a T-shaped post inserted at six o'clock. The Brownells/EoTech T-Dot (#080-000-971) attaches directly to Mil-Std 1913 Rails with a quick-detach lever. It's powered by a single 123 lithium battery, offering 600-hour battery life at the highest brightness setting. The sight weighs 11.2 ounces and is submersible to 10 feet.
