Kriss USA

This is the OEM rear flip sight that is equipped with the KRISS Vector firearms. This sight is extremely low profile designed to tuck completely out of vision when folded sitting a mere 14.22mm above the rail surface. The Rear Sight features two apertures 1.5mm diameter and 4.5mm diameter for different lighting and shooting conditions. Additionally the rear sight folds down completely flat regardless which aperture is in use in order to be as user friendly as possible. Finally the large textured adjustment knob makes windage changes with gloves simple and easy. - DIMENSIONS - Length Folded: 2.25 / 57.25mm - Width at Base: 1.19 / 30.22mm - Width at Body: 1.19 / 30.22mm - Height Folded: .56 / 14.22mm - Weight: 0.75oz / 21.26g - Large Aperture Dia: .18 / 4.5mm - Small Aperture Dia.: 0.06oz / 1.5mm
