Kriss USA Low Profile flip up front sight is the same OEM front flip sight that come standard with the Kriss Vector and DMK22 firearm platforms. The sight provides you with an extremely low profile front sight which will tuck completely out of the way when folded resting at a slim .50″ when folded down in the stowed position. This particular front sight has a wide range of elevation adjustment which will accommodate a large spectrum of height over bores, conditions and calibers. A large textured adjustment knob makes elevation changes simple and easy especially if you are operating with a gloved hand.
