Kriss USA

This is the OEM polymer rear flip sight that is equipped with the KRISS Vector and DMK22 firearms.

The KRISS Low Profile Rear Sight features two apertures, Small Aperture 0.06"/1.5mm diameter and Large Aperture 0.18"/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. Torque spec is 2 Nm (1.48 ft-lb). Sight adjustment based on 14.5" sight radius.
