The Freedom® RDS® is a red dot sight that surpasses other red dots in terms of consistency and durability. Drawing on over 70 years of optics knowledge, Leupold created a tough and reliable red dot sight that performs well in extreme conditions, and is affordable. This sight is a true 1x sight, meaning it has everything needed in a red dot and nothing unnecessary. It is made in the USA, designed, machined, and assembled with Leupold's lifetime performance guarantee. Additionally, the Freedom® RDS® comes with an AR-specific mount. At brightness 4 of 8, the battery life lasts a minimum of 1000 hours. The RDS itself weighs 7.2 ounces without the mount and battery.
