Red-dot optics provide an intuitive sighting system for those with today's modern sporting rifles, thanks to their 1X configuration and easy-to-see dot-sighting arrangement. The Burris RT-1 Red Dot Sight is a dedicated optic for those on a budget and seeking out an easy-to-use aiming solution for their rifle or carbine. Each Burris RT-1 red dot ships with a high and low base mount, which allows shooters to configure the optic to their preferred height. The unit weighs only 4.8 ounces, so it won't add significant weight to your platform, and the 2-MOA dot size allows for confident precision shots without taking away speed. Each optic is powered by a single CR2032 battery
