The PSE Nighthawk Sight is designed with a machined aluminum sight frame, dovetail windage and a pin guard. This sight takes wrapped sight pin technology to the next level. Compared to other sights in the market, its unique metal .029 sight pins provide "zero gap" pin spacing on the same plane, while supporting the fiber over the entire pin length. The fiber chamber is supported by a shock absorbing mounting system that eliminates fiber noise associated with most comparable brands. This sight also performs well under low light situations as its Glo Ring provides an enormous advantage in locating your target. Will accept the Indiglo sight light.
