Leica is the first premium manufacturer to implement its red dot sight with asphere, guaranteeing an even crisper and more brilliant image of the illuminated dot, extremely high image quality as well as excellent viewing comfort. Milled from a single piece of aluminum, the compact and lightweight housing of the Tempus ASPH. is also extremely rugged and robust. The Tempus is available in two different versions: Either with dot size 3.5 MOA for more visibility of the target mark or with dot size 2.0 MOA for minimal target coverage.
