The Aimpoint Duty RDS is a game-changing red dot sight, combining Aimpoint's renowned quality with an accessible price. Designed for modern law enforcement, this compact reflex optic excels in short to medium range engagements with its bright, crisp 2 MOA dot. The Duty RDS features flush-mounted, waterproof windage and elevation adjustments that eliminate the need for protective caps. Its turrets offer audible "clicks" for precise zeroing, and the digital keypad for brightness adjustment is easily operable even with gloves. The sight's pressure-forged aluminum alloy housing ensures durability against severe abuse and temperature changes, while it remains vibration and shock resistant and can be submerged up to 80 feet. Powered by a single CR2032 battery, the Duty RDS utilizes ACET technology for over 3 years of constant-on use at daylight position 7, with extended battery life on night vision settings.
