This product is the Original Equipment Manufacturer (OEM) polymer rear flip sight commonly installed on KRISS Vector and DEFIANCE firearms. With its extremely low profile design, it is intended to completely tuck out of sight when folded, positioning just 14.22mm above the rail surface.
The DEFIANCE Rear Sight stands out with its dual-aperture feature, offering a 1.5mm diameter and a 4.5mm diameter aperture to cater for different lighting conditions and shooting requirements. This multifunctional feature further showcases a user-friendly design that allows the sight to fold down completely flat, irrespective of the aperture in use.
A noteworthy attribute of this sight is the large, textured, adjustment knob that simplifies windage alterations, even when wearing gloves, making it easy and straightforward to use.
