AIM-O has released a Black and DE version of the T1 Red Dot sight. It's made out of metal and incredibly sturdy. It comes with 2 caps on the lens which prevents dust from getting in when it's not in use.
This version sits close to the rail and also comes with a QD low mount so you can provide a lower profile to how your gun is set up. It has an intensity of 5 for both Red and Green dots can be adjusted easily for windage and elevation.
Powered by a single CR1632 3v lithium cell battery
Batteries not included due to IATA airline regulations
