The Duty RDS is based on the battle proven T2 footprint. This red dot was created to fill the gap between the Aimpoint PRO and the T2 for those shooters looking for a smaller footprint red dot without the associated cost of the T2. The crips 2 MOA dot allows for precise point of aim for those lower probability shots while still being fast to the eye for rapid engagement. 30,000 hours of operation at setting 7 allows the user to set the optic without the worry of it not being there when they need it, assuming battery changes happen at an interval. Lightweight and affordable with that proven track record from Aimpoint makes this red dot the easy button.
