This is the same OEM front flip-up sight that is equipped on the KRISS Vector SMG. This sight is extremely low profile, designed to tuck completely out of vision when folded, sitting a mere 12.7mm above the rail surface. The Defiance Front Sight features a very wide range of elevation adjustment, accommodating for a large spectrum of firearms with various height over bore and sight radius measurements. Finally, the large, textured, adjustment knob makes elevation changes with gloves simple and easy.
