The Smith Enterprise M14 tritium night sight is a precision wire EDM replacement for your factory sight. The sight body is machined from 4140 chrome-moly bar stock with a Mil-Spec phosphate finish. The tritium element is placed vertically in the front sight, illuminating the front of the post in low light conditions. This sight is designed for close combat during low visibility; it is not intended for precision shots at extended ranges. The dovetail design will fit both USGI and aftermarket flash hider bases.
