Leica’s Tempus 2 ASPH delivers maximum performance, quality, and durability. This compact red dot excels at tracking fast moving targets such as fleeing game, and allows the hunter to focus on the target with both eyes open for greater situational awareness. The aspherical glass lens features the same level of clarity that all Leica optics share, and the crisp 2.5 MOA dot is easy to see in all lighting conditions. The Tempus 2 ASPH is precision machined from a solid block of aluminum, giving the optic outstanding strength and impact resistant up to 1000g. The Tempus 2 ASPH’s durability is enhanced even further thanks to a semi-transparent quick-release cover made from soft silicone, and can be attached/removed with ease. In addition, the optic features over 3000 hours of battery life (at medium brightness), and features a motion sensor to automatically switch off the optic when the rifle comes to rest to preserve battery life.
