The Wilson Combat high profile Vickers Elite Battlesight rear has a .145" wide, deep U-Notch for optimum sighting in low-light, dynamic range conditions and is a perfect match to the Wilson Combat .125" wide front sights. The concave non-reflective rear blade is serrated 40 lines per inch, while the notch area is recessed into a semi-circular pocket for a crisp, protected sight picture. Two hardened set-screws ensure this sight will never shoot loose under the most demanding conditions. This snag-free rear sight also has a shelf shape that enables one-hand slide cycling or malfunction clearance. The high profile of the Vickers Elite Battlesight allows the use of a taller front sight and deeper rear notch for better sight tracking during high speed shooting situations.
