When shooting at extreme ranges, many shooters find their riflescope lacks the necessary elevation travel. The Nightforce Wedge Prism is offered in 2 variants, 50 MOA or 100 MOA, that install forward of the riflescope to increase the effective elevation travel. The Wedge Prism optically shifts the incoming image to the riflescope by a precise elevation value, which directly adds to the available elevation travel within the riflescope.
