The Konus Pro AS34 has been constructed with quick target acquiring properties. Thus, speed and accuracy have both been enhanced whether at the range or in Close Quarter Battle (CQB) situations. A beffy outer diameter of 34mm can withstand the most extreme conditions. An integrated tri-rail accepts all your accessories. Completely waterproof with a dual illuminated, etched mil-dot reticle for low light shooting, and a wide angle field of view for fast moving targets. The included base will mount on weaver or picatinny rails, as well as a 3/8" dovetail rail.
