Developed by Bill Wilson specifically to meet the needs of the Beretta 92/96 shooter, this Beretta Battlesight tactical rear sight has a .150 wide, deep rear U-Notch for optimum sighting in low-light, dynamic range conditions. The concave rear blade is serrated 40 lpi, while the notch area is recessed into a semi-circular pocket for a crisp, protected sight picture. Drop-in, fit on Beretta 92/96 models with rock solid set screw retention. Machined external front shelf enables one-hand slide cycling or malfunction clearance. Standard factory replacement rear height is .270" with a solid post front sight. *Note-For Beretta 92/96 models with front sights integral to the slide select different rear heights to modify your pistols point of impact. Raising the height of your rear sight by .010 will raise your point of impact approximately 1.7 at 20 yards.
