Blaser’s RD20 Red Dot Sight was specifically designed for their line of premium rifles, and features the precision and quality that comes standard on all of Blaser’s products. It comes equipped with Blaser’s own saddle mount, which allows it to seamlessly integrate with the host rifle. One of the RD20’s main characteristics is a large interior diameter that keeps target blockage from the housing to a minimum. This helps facilitate quick shots, making it an excellent choice for driven hunts and close range shooting. The RD20 also features Blaser’s exclusive Intelligent Illumination Control (IIC). This feature automatically switches the optic off when the rifle’s muzzle is pointed up or when the rifle is in a resting position, as well as an automatic shutoff six hours after the last button operation – making manually switching the optic off at the end of the day optional. The IIC function will then immediately activate the optic when the rifle is raised to a firing positon. This energy saving aspect gives the RD20 an amazing battery life of 50,000 hours. In addition, the RD20 comes standard with scratch-resistant lenses, and coatings that easily shed water, snow, and other debris.
